GenomeLink Review: Accuracy of DNA Trait Reports

I’m always on the lookout for more things to do with my DNA results from AncestryDNA or 23andme—especially if they’re free or low cost. When I find said things, I also like to share them here, and well, I found a thing. GenomeLink is a DNA service that analyses your rawDNA to offer insight into lifestyle, nutrition, cognition, and personality genetic traits you may possess. This is done by checking your rawDNA against a list of single-nucleotide polymorphisms (SNP) that have been linked by research to certain traits. If you’ve tried Promethease (which costs $12), the service is similar in mechanism, but offers far less data in a more digestible format and focuses less on medical traits.

Alright, let’s get to it..

 GenomeLink review:

With a free account you receive 20 trait reports, or maybe 30, as their sign-up page lists 30, and their plan page lists 20. I counted 30 in my actual report. I’ll admit, I found the site itself a little poorly edited. Some links didn’t work. You couldn’t use the trait scroll bar. Some links didn’t do what I expected they would. It all sort of has a “beta” feel to it to me, but you know, if the info is good, I don’t care much about that.

The company did reach out to me after reading my AncestryDNA vs 23andme comparison and offered me a free upgrade ($39 value) to add to this review. This review wasn’t paid, and obviously I didn’t allow that offer to sway my review to insta-five-stars. My reviews are always unbiased. That upgrade added another 30 traits, and I’ll get a new trait in my inbox every Sunday.

Now I actually wouldn’t have needed the upgrade. I have to say most of the traits offered I had already seen either in 23andme’s health reports or Promethease’s data, and I’m sad to say I question the accuracy.

As a side note here, I am aware that having a genetic tendency for something doesn’t guarantee that it will present itself. I’ve had plenty of other genetic insights tell me things like I should be lactose intolerant, and I should have the long luxurious locks I’ve always wished I did have. The reason I question the accuracy of this service is that I have comparison data.

For example, here’s the first report from my GenomeLink account: Eye color.

genomelink review

Ignoring the horrible grammar in this screen shot (or not?), Inconclusive? They couldn’t tell me what color eyes I probably should have, but they could tell me there’s an equal chance of brown, not brown, or intermediate (huh?). Now, let’s compare that to 23andme and Promethease….

23andme says my chances of blue, green, or a mix are 90 percent (my eyes are in fact blue green) and that brown has the lowest chance. There’s no thirds about it.
23andme eye report

Promethease gave me too much data to screenshot it all for you, so you get just a small section, but to summarize, there were 14 markers associated with a higher chance of blue, green, or grey eyes, several giving a 99 percent chance, and not a single flag for brown.

promethease eye color

Basic genetics makes that a logical finding being my parents, my grandparents, and their parents, all had blue or green eyes.

Many of the other traits listed in my GenomeLink report also didn’t match 23andme and Promethease’s reports (which did agree), and often they said the complete opposite. For instance, Genomelink claimed I was unlikely to have freckles, the other two reports said I was likely to have many. Genomelink said I had a 100 percent chance of having strong skin pigmentation. The other two said “very fair,” and I glow in sunlight, so that’s an accurate description.  I could continue, but I think the point is grasped.

If I had to guess, it’s actually the limited scale as far as the number of markers GenomeLink analyses that hurts it. In the eye color example, they looked at three markers, had they had a wider view, the strong chance of blue or green eyes would have been more statistically clear. This hypothesis is supported by the fact that of the 60 traits I had access to 18, almost a third, were inconclusive.

My overall impression of Genomelink was it is, in fact, a little beta, and the site really seems to aggressively push the up-sale. With some work on accuracy and site design, it’s a cool concept. If you tested at AncestryDNA it would give you access to the genetic tidbits you missed out on by not testing at 23andme without the data-overload of Promethease. The new traits in your inbox is also very calendar-of-the-day trivia-cool. I would definitely dig that it if I could trust the info I was being given.

As-is though? I would say go for the free version for kicks, but give it some time to see how they grow if you’re interested in the upgrade.

Best DNA Test for Genealogy: AncestryDNA Review 2019

AncestryDNA and 23andme are arguably the most popular autosomal DNA testing options around, but which is the best DNA test for genealogy? Is one test better than the other for finding family? One, in fact, is. AncestryDNA offers a far superior product if your goal is to build a family tree, trace or discover familial lines, or find new family members. The aim of this page is to not only offer an in-depth AncestryDNA review, but likewise explore the area where Ancestry DNA’s test really shines—genealogy.

We also have a full comparison review of 23andme vs AncestryDNA and an in-depth 23andme review.

AncestryDNA Tree building and research service:

One major difference between 23andme and AncestryDNA as far as genealogical research use, is that AncestryDNA eliminates the need to create a tree off-site, find records at various sources, and then compile everything and compare it to your DNA matches. You can build a tree entirely free on the AncestryDNA site, though to utilize research options there is a subscription fee. With your purchase of an AncestryDNA test, you get 50 percent off this service. Subscription costs and levels as of May 2018 are as follows:

AncestryDNA test cost: $84+ shipping from with this referral link or $99 with prime shipping from Amazon
US subscription: Allows search of US databases only: $22.99 monthly or $49 for 6 months
International subscription: Allows search of worldwide databases: $34.99 monthly or $99 for 6 months

Your subscription allows you to:

-Search, view, and save files from a large database of records including birth, death, marriage, immigration, census, newspapers, and more.
-View “hints” that automatically suggest records and other member trees based on data entered.
-View connections you share with your DNA test matches.

Ease of connecting the DNA dots:

The primary reason AncestryDNA boosts the best DNA test for genealogy and family finding though is not it’s research tools, it’s the ease of tracking down match connections. While at 23andme you would need to contact each match to find out if they even have a family tree, AncestryDNA streamlines this process by allowing you to sort matches with trees and even see where your tree (assuming you have one) overlaps with that match’s tree. You simply click the tree icon, and the connection pops up.

Once you click into a match you can then view that match’s tree (if public), shared surnames and tree members, shared matches, and regions where shared tree members originated. Each of these options is useful in its own way.

best DNA test for genealogy

For example, shared matches are an easy way to determine which side of your family a match is on if you already have confirmed relations in your matches. Say, your mom, dad, an aunt or an uncle have tested, depending on those your match shares you could quickly see if a match was paternal or maternal.

On the regions tab, say you have a name for an ancestor, but don’t know where the ancestor was from. Your regions map can help narrow down where to focus your source search for possible matches to that ancestor.

Automatically generated genealogical goodies:

Your DNA story:

This is the page that gives you your ethnicity report. If you click any ethnicity, it will show you a percentage match for the sample pool of that region, as well as locations included in that region.
best DNA test for finding family

As you click the timeline bar at the bottom, the map will change showing you the migrations of your family line through time (requires a tree) while likewise circling the regions your DNA results showed. The pinpoints that display either numbers or a pink or blue profile are ancestors in your tree. You can click each to see details or in the case of numbers, to zoom in to see all tree members in that area. I wouldn’t say that this feature really aids in research much, but it is neat and provides a quick way to compare your genetic ethnicity to your genealogical origins.

DNA circles:

In this section your tree is compared to those of your matches to create “circles” of people who share an ancestor. The name of that ancestor is the name of the circle. For example, if the circle is called “John Smith,” you had a DNA match with all of these members and all of these members have “John Smith” with the appropriate birth and death data in their tree. This is a convenient way to have numerous sources with a confirmed DNA match to compare notes so to speak on certain parts of your tree.

New ancestor discoveries:

Basically, this is DNA circles for potential ancestors not already in your tree. Say that many members in your “John Smith” circle have listed John’s parents, but you don’t have those parents in your tree. This section shows you the details of those high-probability tree members. If you click one of these results, you’ll be shown the circle that prompted this match and how many matches had the suggestion in their tree.
best DNA test for genealogy

Database size:

The final AncestryDNA section is your matches for the database. Next to the ease of connecting tree members to matches, this is the second biggest reason AncestryDNA is better for genealogy than 23andme, database size. As of May 2018, AncestryDNA boosts double the database size that 23andme has (5 million vs 10 million). If your trying to use DNA to find family or trace your family tree using DNA matches and can only afford one test, the bigger the database size the better.

Having a look at the match screen, you can see at the top there are several options to sort your matches.
-Hints will show you members that you share a common tree member with.
-New will show you new DNA matches.
-Starred will show you members you mark with a star to quickly find later.
-If a parent comes up in your matches you’ll see “father” or “mother,” this allows you to sort matches from your maternal or paternal line.
-Regions gives you an option to select a migration region from your timeline, and see matches that share that region.
You can also filter by relationship closeness (example, a sibling would appear higher than a cousin) or date of match (to see matches since your last visit for instance).
best DNA test for family finding

While 23andme may offer more nifty genetic tidbits to amuse you, it offers none of the above family finding tools. This is why if you’re looking for the best DNA test for genealogy, I’d recommend starting at AncestryDNA and only testing at 23andme if you hit a wall and need more matches or just are interested in said genetic niftiness. You can also upload your raw DNA (which is free with your test result, of course) to GEDcom, a mostly user-submitted DNA match data base as well as FamilytreeDNA. FamilyTreeDNA will allow you to upload your results and see limited matches, but there is a fee to see more. GEDcom is free. You can’t, by the way, upload your raw DNA to 23andme, you would need to retest to see your matches there.

If you have any questions or see something I missed here, feel free to drop me a comment.

23andMe Review 2019: Are Health Reports Worth the Price?

23andme now offers two different DNA testing “levels” so to speak. You can get just the basic DNA test that comes with genetic heritage reports, DNA matches, and more for $99 or you can get the basic test plus health related genetic reports for $199. That might leave a lot of you wondering if those genetic health reports are really worth more than double the price. So, let’s take a good look at what you get with each testing option so you can decide for yourself. You can also read a comparison of 23andme’s basic testing level and AncestryDNA’s test right here.

What do you get with the basic 23andme testing level?

The basic 23andme test comes with two main components: genetic heritage and DNA matches.

Genetic Heritage:

Not to be confused with your genealogical heritage, genetic heritage will tell you where your actual genes came from. Confused? Genealogical heritage refers to where the actual people in your family tree were from. (IE, Grandma was from Norway.) Genetic heritage refers to where the DNA you actually have came from. I often tell people to think of their genes like a bag of dice composed of all of their ancestor’s genes (Grandma included). Which of those genes makes up you really depends on a roll of those dice meaning where those genes originated from geologically may also vary from where your recent ancestors were from.

23andme review 201823andme checks 31 primary DNA sample populations broken into 151 sub-categories. The actual regions percents are given for include Western European, British and Irish, French and German, Scandinavian, Finnish, Southern European, Iberian, Sardinian, Italian, Balkin, Eastern European, Ashkenazi, Native American, East Asian, Japanese, Korean, Yukat, Mongolian, Chinese, South East Asian, West African, East African, Central and South African, North African, Middle Eastern, Oceanian, and finally unassigned.

The test will not separate “and” categories. For example, you will get one percentage for “French and German” not one for French and one for German, but these primary regions can be viewed in more detail as a match strength your genes showed to sample sources from individual countries, such as “France” and “Germany.” This strength is not given as a percentage. Below is my full report from this more in-depth section, you reach this report on your results by clicking “See all tested populations.” I’ve included all the regions, even those I had no match for, so that you can see the entire 151 country list. Alternately, here is 23andme’s help page listing their reference populations.

This also gives you a better idea what each region includes. Many are confused by the “Native American” region in particular. Most think of Native American as the tribes we’ve come to know today in North America such as Cherokee or Blackfoot, but 23andme is using data samples from mostly South American countries (which are still native to the Americas). This is because, in 23andme’s own words, “In North America, Native American ancestry tends to be five or more generations back, so that little DNA evidence of this heritage remains.”

Your report will show in a single scroll-able page, the one shown here was created in paint from multiple screenshots for a better page fit on the page (sorry mobile users). The more dots a country has the higher likelihood that you had ancestors from the location. For example, 48.2% of my DNA is “British & Irish” with a strong chance that many of those ancestors were from the United Kingdom rather than Ireland. As you can see, not all percentage regions are able to be broken down into a likely country of origin. In my sample here, 12.8% of my DNA is “French & German,” but 23andme was unable to determine which country that percentage was probably from.

You can also view your results at 5 different levels: 90, 80 or 70 percent conservative or 50 percent speculative. Each of these levels guesses to some degree based on regional samples where segments of your DNA originated and then builds a percentage of your full genome from each area. The default report (pictured above) is set at 50%. To view other settings, visit the main ancestry composition page (the one you clicked “See all tested populations” on) and scroll down until you see, “Your Ancestry Composition Chromosome Painting,” then click, “Change confidence level.”
23andme review

This report is only given for the 31 sample regions, not the full 151 country report.. At the bottom of the detailed 151 country report page there is a confidence level selection drop box, but that only affects your raw DNA data file. The first image below is a comparison of the raw DNA files that are used to build the chromosome painting at 50% vs 90%.

I did not include the entire report, because there are 144 cells (the reports are in Excel) and that would make for a very long image, but you get the idea. I included the file names, because the “.5” or “.9” in this case are how you can tell what the report was set at.

These images below, on the other hand, are my actual results for 90 percent conservative and 50 percent speculative on the chromosome painting page (I know, it is annoying they are not in the same place). As you can see, the more conservative the guess, the more “broadly” percentages you will get. While the more “speculative” guess will assign higher percentages to actual regions.
23andme review 2018 23andme review 2018

If your parents test on 23andme, your composition will also update based on their results, you can read more on this process here. A comparison of how my results changed when my mother tested are shown below. The visual differences in the report are because the without-parent results are from before 23andme updated and redesigned their site appearance. 23andme review
When viewing your matches you can also compare your DNA side-by-side to your parent, and if one parent has tested but the other hasn’t, a guess will be shown for the second parent’s genetic ancestry (since you get 50% of your DNA from each parent).

Also included on the ancestry composition page is your ancestry timeline. It shows where within your ancestry certain genes were likely to have come from. You can hover over each bar and a pop up will elaborate. As seen below.

ancestry timeline 23andme


Moving on to the next report, haplogroups. Everyone gets their maternal haplogroup, males will additionally be given their paternal haplogroup. Haplogroups are groups of genes that are believed to be common to a particular genetic ancestor. This in theory would reveal where the very first person in your genetic line originated from– the birth of your gene line both maternal and paternal. Below are my maternal results. To get my paternal results, my father or brother would need to test. As an added well-that’s-nifty throw in you’re also shown a common ancestor who shares your haplogroup. I got Marie Antoinette!

Neanderthal DNA:

The final genetic heritage section is neanderthal DNA. Here you are told how many of your genes are neanderthal variants. To gauge how high or low this number is you’re also told how much of your DNA is neanderthal and how this compares to other 23andme testers.

23andme review neanderthal

The test also shows four traits common to certain variants and tells you if you have those variants. One for a likelihood of having straight hair, one for a likelihood of sneezing at dark chocolate (this is apparently a thing), one for a lower likelihood of back hair, and finally, one affecting height. You are also ranked against your family and friends (those you have confirmed relation with).

23andme review neanderthal
DNA Relatives:

The other primary component of the basic 23andme DNA test is DNA relatives. This section compares your DNA to all other testers and then provides you matches. Each match lists a probable relation (example, second cousin) as well as the amount of DNA shared.

23andme DNA test match screenThese matches can be searched or sorted by relationship, mom or dad’s side (if your parents have tested), the number of grandparents a match has with the same birthplace, and surname. The surname field also gives a count for each name ranking them from highest to lowest. This is quite helpful to quickly spot likely genetic lines.

When clicking into a match you are given more detail, including common surnames, locations of common ancestors (such as, say, you both said your grandma was from Norway), haplogroups, and genetic heritage. How much is shown depends on how much you and the match have elected to share. This screen also allows you to contact your matches or choose to share more information. Unlike AncestryDNA’s match screen, 23andme regrettably lacks family tree matches.

Ok, now what do you get with the genetic health reports upgrade?

When ordering the $199 test from 23andme, you receive all of the above along with genetic health reports. These reports check for genes known to increase chances for certain conditions or traits. Please keep in mind that having the genetic predisposition for something doesn’t promise it will present itself. For example, my health reports gave me a high chance of being lactose intolerant. I’m not. There are 41 health condition carrier reports, 19 traits reports, and 7 wellness reports. Below is a full list of carrier reports.

23andme DNA Test Traits reports measure your chances of having certain physical traits. These aren’t super vital to most people, as, well, we have eye balls and mirrors, but it is cool to see how much is actually a result of your genes. Trait reports include:

  • Asparagus Odor Detection
  • Back Hair (available for men only)
  • Bald Spot (available for men only)
  • Bitter Taste Perception
  • Cheek Dimples
  • Cleft Chin
  • Earlobe Type
  • Earwax Type
  • Eye Color
  • Finger Length Ratio
  • Freckles
  • Hair Curliness
  • Light or Dark Hair
  • Male Hair Loss (available for men only)
  • Newborn Hair Amount
  • Photic Sneeze Reflex
  • Red Hair
  • Skin Pigmentation
  • Sweet Taste Preference
  • Toe Length Ratio
  • Unibrow
  • Widow’s Peak

Each report gives more detail on your likelihood of having each trait and how that compares to other users of a similar background.

23andme review DNA

Wellness reports on the other hand look at lifestyle and health-related traits, such as the before mentioned lactose intolerance, as well as alcohol flush reaction, caffeine consumption, deep sleep, sleep movement, muscle composition, saturated fat, and weight.

As of 2019, you can also connect your results to the Lark Health Coach app to receive diet and exercise advice based on your genetics. The free version of this app is limited and only includes sleep and activity tracking via your phone’s sensors (you may not link wearable devices such as Fitbit unless they will tie into your phone’s default program). There are also two more comprehensive programs that run $19.99 a month– the Wellness program which includes diet, exercise, sleep, and activity tracking, and the Diabetes prevention program, which may be covered by your insurance. I did not subscribe to this service and can’t offer a user review as a result, but it could potentially be a perk for someone choosing 23andme.

Are the genetic health reports worth the money?

Sadly, 23andme must not realize you can pay for the standard test, download your raw DNA, and get health reports for $12 from Promethease. Worse, the Promethease report is far more detailed albeit more complicated and not FDA approved. What little 23andme told me matched what was in my Promethease report (23andme actually contributes to the database Promethease uses), but the Promethease report had thousands of matches (over 22,000). Below are a few screen cuts from my report back in 2015, as you can see, they flagged genes for all sorts of stuff.

promethease promethease DNA health report

Even the updated Neanderthal info was on Promethease, but more genes were flagged.

Personally, I would not pay $199 for what I could get for $99+ $12 just to have it look pretty. Whether or not you would is up to you.

Promethease also redesigned their reports sometime between my original running in 2015 and now, so I paid again just to review their “prettier” report for you (results do not stay online forever, but can be downloaded). You can read our in-depth Promethease review here.

Remember that at 23andme every additional test you purchase is 10% off and shipping is combined, so you could save by finding others who would like to test and do a group order. 23andme is also now on Amazon Prime (basic test and genetics health reports version). If you want just one test, you can save on shipping this way.

I do hope this has helped you reach a decision between the $99 23andme DNA test and the $199 23andme genetic health reports test. If you have any questions or would like to see something added to this 23andme DNA test review and comparison, please let me know.
