I recommend one of two options. It may cost a little more, but I would highly recommend saving the extra and using DNA Tribes® rather than spending over half the cost for minimal tribal/biogeographical pinpointed information. The primary benefit of STR rather than SNP testing is the availability of rich reference data. DNA Tribes® tests industry standard autosomal STR systems, which allow the identification of a person’s DNA profile not shared with any other person. Because these STR markers have been tested and used in the court systems around the world, they allow DNA Tribes® to perform the most thorough comparison of a person’s own DNA profile to over 1,200 ethnic groups (populations) around the world. At present, SNP testing from these other autosomnal DNA testing kits does not yet match the geographical detail of DNA Tribes® autosomal STR analysis.
Every company providing DNA testing has their own database of DNA samples. These are called AIM’s or ancestry informative markers. These markers were derived from the current populations of America, Asia, Europe and Africa. Every database is looking for a pair of genes located on a specific chromosome in a specific position. The way the DNA is evaluated is through the SNP’s or the single nucleotide polymorphisms. The SNP’s are chosen according to the frequency in a specific geographical population. Your SNP’s are compared to the most common SNP’s for the various populations in the company’s reference database. The results are not conclusive because they are based on common genetic variations. The probability for your DNA being from a certain country is based on a comparison between your DNA and the database. If you used a different company, they would have a different database. This means your results would most likely differ. According to studies, the lowest concordance is with individuals of South Asian, East Asian and Hispanic descent.
When I found out about AncestryDNA, I thought this could be the perfect tool to pinpoint where my family emigrated over the past few hundred years (AncestryDNA can actually go back 1000 years) and give me a focus where to take my search next. When I got the email that my results were ready I felt like a kid on Christmas day. They revealed that I was only 40% British, 25% German and 35% Greek. I’ve now focused my search on these three countries and already discovered ancestors I never knew existed.
My own results are eagerly awaited: the whole process takes about 6 weeks. I am somewhat more sceptical having Polish heritage and therefore my contact with relatives might be less likely, however I am waiting eagerly to see whether I have any trace of the Mongol hoards who invaded deep into Europe. I have posted a screenshot of how long the process takes from activation.
DNA Diagnostics Centre offers a range of exciting ancestry testing services. Whether you’re looking to discover the origins of the maternal or paternal side of your family or you wish to determine your genetic profile and learn how much ancestral DNA you have from European, African, indigenous American or Asian peoples, we have the right test for you.
If you opt in to DNA Relatives, you will be able to send and receive invitations to connect with other customers who share DNA with you. You can choose whether to respond to these invitations or not, and your DNA relatives have the same choice. We cannot guarantee that they will respond to your sharing invitations or messages. Regardless of whether you both agree to share, you will be able to see their birthplace, locations of their ancestors and surnames, if they have chosen to add this information to their profile. If you both accept sharing invitations, you will be able to see ancestry reports and overlapping chromosome segments.
The first kit I try is Thriva’s baseline test (£49), which, like all its products, checks your blood. The box arrives promptly enough (containing spring-loaded needles, a little collection tube, antiseptic wipes, plasters, etc), but there’s a problem. The idea is to prick your finger and massage blood into the tube, but I just end up making my fingers sore and what I get out barely smears the top of the phial. Maybe it’s just me, but it turns into a right faff. In the end, I take advantage of Thriva’s service to send someone out to take a sample of blood from my arm.
