In addition to its ancestry test, 23andMe also offers a cool health upgrade. The upgrade costs $125 if you add it after getting your ancestry results, so we recommend splurging and buying the $199 Health + Ancestry kit from the start and it often goes on sale. It was approved as the first direct-to-consumer genetic screening service by the FDA in 2015 for certain conditions including Parkinson’s disease and late-onset Alzheimer’s disease. Many of the service’s 87 health reports are much more lighthearted, however, including information about your probability of disliking cilantro, getting bit by mosquitos or having a longer index finger than ring finger.
A. Be aware of DNA tests advertised at this price. DNA Clinics have received calls from many anxious individuals who have had these DNA tests carried out for £59 only to realise that the test has been performed at an overseas non UK accredited laboratory. DNA Clinics most affordable test is a Peace of Mind Paternity DNA test available for £119 from www.homednapaternitytest.co.uk. Whilst this is more expensive than the £59 DNA test, you have the reassurance that all testing has been performed at Crystal Health ISO17025 accredited laboratory using strict chain of custody protocols.
23andMe has also been the target of concerns over how they handle user data. Their tools are more advanced than what AncestryDNA offers, and the International Society of Genetic Genealogists claims that they have the most accurate admixture results – but many in their database are health testers and may not be receptive to matching for genealogy purposes. They also offer no family tree integration at all.
Testers appreciated the amount of information and context given with each report. For example, the regional ancestry report matches your DNA to broad world regions on a map, but it also compares your DNA to two more-specific reference populations. My regions were Northeastern Asia and South China Sea, which fit the Korean and Japanese reference populations. Another tester was matched to 11 geographic regions throughout Europe, North America and West Asia, and they were matched to Argentinian and Puerto Rican reference populations.
In the case of a great-grandchild, or a great-great-grandchild, something even stranger can happen. Remember that a child will get half of their mother’s DNA, but there is never ever guarantee which 50%. The way it is chosen is fairly random, as far as scientists know. Take the example of the 100% Eastern European person. Their great-grandchild will inherit 50% of their DNA from their part-Eastern European parent, but there is a good chance that they won’t inherit all of the Eastern European DNA that they could potentially inherit. It’s possible for a person to share NO DNA with a great-great grandparent, even though there is a verified genealogical relationship.
As it happens, most of the data on 23andMe seems harmless and fun. There are the “Neanderthal variants” (I have fewer of them than 58% of 23andMe customers, thank you very much), the bizarre earwax/earlobes-type data and, apparently, I have the muscle composition generally found in “elite athletes” (fancy). On the downside, my lineage isn’t as exotic as I’d hoped: 99.1% north-western Europe, of which 71% is British/Irish, with just 0.01% “Ashkenazi Jewish” to offset the genetic monotony. At £149, the 23andMe kit isn’t cheap and I’m quite tempted to demand a recount.
Nacho Esteban of 24Genetics told us, “Ancestry is not an exact science. The top five companies in the world would show very similar results when talking about continents; the similarity is smaller when talking about countries. In regional ancestry, some border regions are difficult to identify and sometimes there may be discrepancies. So we cannot take the information as something 100% sure. But at the end, it gives a great picture of where our ancestors were from.”
I was given a picture of myself I believe I was about two or three years old, I have always thought I was born in the USA, BUT TO THE BOTTOM OF THE PICTURE SAYS HAVANA STUDIOS, ALSO I WAS BORN IN A HOSPITAL 1958 HOWEVER THE HOSPITAL WAS DAMAGED IN A HURRICANE AND DID NOT OPEN UP AGAIN UNTIL 1959 BOTH PARENTS ARE DECEASED AND GRANDPARENTS ARE DECEASED WHICH WILL BE THE BEST TEST. OH NO KNOW SISTERS OR BROTHERS.
I used 23&me, (who has around 80 geographical regions) and while I was disappointed with the nationality results, it was only because I thought they were a bit vague – but in all honesty, I didn’t really know what to expect, so there’s that. Now understanding a little more about the limitations of results from any company, have no problem with what I received.
MyHeritage shows cousin matches as part of your DNA purchase for free and has some really wonderful tools to connect your research to your DNA matches. Using smart matching features to see how your tree is connected to others, and adding records you discover this way, may cost an additional monthly fee however. Still, MyHeritage is generally less expensive than Ancestry. You can also try their record collections for free here.
Lets suppose, as we have in the Sinnott/Sennett one name study, we have a whole lot of families who all believe their common ancestor came from Co Wexford, but the paper trail for conventional genealogy research has dwindled away, or we suspect that John and James who emigrated to the US about the same time were brothers but there is no documentation to prove it – genealogical DNA studies can now be used to show whether its possible that two families (that are at the moment quite separate on paper) are actually related and have a common ancestor. And no, we don’t have to go digging up g-g-g-g-grandfather John to get his DNA – remember, he passed it on to his son, and his son’s son, and so on to the present day. So we find a living male descendant and they get their Y-DNA analysed. That gives us a pretty good indication of the genetic signature for the whole family tree (well, the male side, anyway). If we want to check it, we find a distant cousin of the first person who tested and get their DNA analysed. If its a very close match, then bingo – we know the Y-DNA genetic signature (and whats known as a haplogroup) for our whole family group.
Autosomal DNA Tests: These type of tests have become extremely popular over the last couple of years as prices have dropped and the amount and accuracy of the results has increased. Autosomal testing looks at information across the genome to provide clues to our personal ancestral history on a much broader scale than either mtDNA or Y-DNA testing can. While this type of genetic testing is an ever evolving science, you can expect to get a general breakdown of your ancestors’ geographical origins (your admixture) as well as connections with people who share your ancestry. This can be a unique and exciting way to tear down those brick walls and uncover branches of your family tree you never knew you had. For some, the results can be surprising and enlightening–for others, there can be a simple verification of already known information and even some disappointment in discovering nothing new.
