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.
DNA profiling can also be useful for those who suspect there may be inheritance disputes over their estate once they have passed away. It provides a record that can be referred to long after someone’s death, even when all physical traces of DNA have gone. Therefore, if there is an unexpected claim for inheritance from an alleged relative, your DNA profile can be compared to that of the claimant to prove or disprove a biological relationship and the inheritance rights.
Generally speaking, those people who have tested with FTDNA, AncestryDNA or MyHeritage DNA have done so for genealogical purposes (even if it is only curiosity about their family’s past) so the response rate from contacted matches is fairly decent. Oftentimes matches are open to being contacted by relations and are eager to compare trees. This is, of course, not always the case, but we have found it to be true for the most part.
Even though we are all unique, most of our DNA is actually identical to other people’s DNA. However, specific regions vary highly between people. These regions are called polymorphic. Differences in these variable regions between people are known as polymorphisms. Each of us inherits a unique combination of polymorphisms from our parents. DNA polymorphisms can be analysed to give a DNA profile.
We similarly advise caution for the multitude of non-diet health and wellness DNA tests, which offer insights into your sleep, food sensitivities, and vitamin and mineral levels. And double that for medical information found in consumer DNA kit test results. While medical insights learned from taking an at-home DNA test may be interesting, it’s best not to take them too seriously. If you have a concern about a genetic predisposition to a disease, it’s best to talk to your doctor instead of relying on a direct-to-consumer kit.
A. DNA Clinics do not offer free DNA testing. The service in the UK for establishing genetic biological relationships is predominantly carried out by the private sector. The NHS does not offer DNA testing for paternity or other relationships. Companies offering free DNA testing are falsely advertising the service. DNA Clinics provide the DNA test kit free of charge, with payment for the test due on return of your samples.
Is this a perfect method? No, but it’s a good way to get a general idea about where your ancestors were from. Genealogical DNA tests can tell you a lot about your ancestry going back 300-500 years in time, for the most part. They can also tell you a little bit about your ancestry going even further back. This is why comparing your DNA to those whose families have stayed in a particular area for a long time is a fairly accurate way to perform the estimate.
For these reasons, mapping segments of your autosomal DNA to whole continents can be determined with a high level of certainty, but when you try to attribute these segments to specific tribes, regions or even countries, the certainty decreases. This is why some genetic ancestry companies will attribute a proportion of your DNA to areas such as ‘Eastern Europe’ or ‘Southern Asia’, instead of to specific countries.
— Once you have chosen a test and received your autosomal results there is still a great deal more fun to be had. Independent tools and websites created by scientists and enthusiasts allow you to take the raw data provided from FTDNA, 23andMe and Ancestry DNA and explore them in astounding detail–giving you a wide variety of new admixtures, phasing options, chromosome browsers, SNP tools and connections with family across the world. Gedmatch is our favorite because they have so many wonderful and meticulously updated tools from a variety of sources. Easily upload your raw data and run your results for free (if you love the tools, don’t forget to donate and uncover even more options.)
