Best company to use with the largest reference database! Just go for it!
November 12, 2017
The beginning: I started with 23andMe, then moved on to Ancestry DNA. I wanted to see if there were any differences. There were a couple. The main two differences were:
1) 23andMe showed a 40% range of Irish/British (zero Scandanavian) and Ancestry showed 50% range Scandinavian (zero British/ 3% Irish).
2) 23andMe showed .08% African (zero West Asian) and Ancestry showed 4% West Asian (zero African).
This had me REALLY confused, so I decided to look more into how the DNA testing process works, along with all of the details I thought I already knew from previous research.
These DNA testing companies are able to give results based on their detailed research they have done on a reference population. It is different for every company. The main thing to keep in mind is the size of the reference group. The larger the group the more accurate the results. MyHeritage makes their testing available Internationally. People around the globe are doing this testing adding to this reference population. Via DNA testing company ways they are able to map different algorithms and locations to find where people in those regions would be from.
Previous tests vs MyHeritage:
1) My testing with MyHeritage was able to tell me that the reference group that Ancestry DNA had was more accurate. Knowing that many of the British and Irish (23andMe) people migrated from the Scandinavian region, somehow these tests were able to track that. This was done likely through the comparison using algorithms of people who share DNA SNPs in both Scandinavia and Britain/Ireland. Knowing that Scandinavia is the original location these people migrated from, these tests were both able to show that I am over 50% Scandinavian and not British at all (with much greater detail in reason than I am knowledgeable about of course).
2) My testing with MyHeritage was able to tell me that the reference groups that 23andMe had, agreed that I have African DNA. Whatever the DNA segment is, it simply isn't in Ancestry's system. Ancestry DNA was unable to locate it and put a name to it like the other two tests did. BUT...Not only was MyHeritage able to verify for me that I was African, but it was able to pinpoint the location to KENYA. Some people from a Kenyan bloodline had gone through the testing and become part of MyHeritage's reference DNA. People from that area had a specific gene that lined up with one I have that showed up in my test. This along with a ton of other factors (SNP's tested and algorithms and other gene carrier factors) proves the Kenyan heritage.
The main reason for MyHeritage DNA is by having the largest reference group and the fact that I was able to compare between these three companies myself and was able to see these differences. I can see how this company is on top as many online reviews and top lists place them. The fact is your family members can tell you your entire life where you are from. Until you or they are tested, there really isn't any way in knowing. Yes, my grandfathers parents were from Poland and spoke Polish and immigrated to the US. But does this mean that they didn't have any blood from West Asia or even from the Iberian Peninsula from their personal heritage as well? Of course not!
This is where MyHeritage DNA is proving to be on top!
**Don't forget! Your DNA doesn't change, but the population group does! As time progresses and more advances in technology are made your results may transform and become more and more accurate! I mean, really, it's a guessing game any way you look at it. MyHeritage is in the top! Forget 23andMe (except for the Health part, that stuff is great) and forget Ancestry DNA (except for their tree stuff, those Mormons really like helping out their dead family members, apparently that's a thing..and it makes their Tree system great as well).
Summary: MyHeritage is the best company. Just go for it!
