When I took my first DNA test in 2016 I was disappointed, in part because I didn’t do my research, so my goal in this review is help others avoid that scenario. Beyond ancestry tests, there are companies that recommend wines or exercise regimens based on your DNA. With all the available options, it’s easy to default to a recognizable name, which isn’t necessarily bad. But certain tests do specific things better. Our goal is to match your expectations with the test that fits best.
Of the 23 pairs of chromosomes in the human genome, 22 are autosomes. Most direct-to-consumer DNA tests look primarily at your autosomal DNA to determine your geographic ancestry percentages. This DNA is a mix of inherited DNA segments – half from each parent. Because everyone inherits at least one X chromosome from their mother, DNA tests often include the X chromosome in autosomal testing, though the X chromosome is not an autosome.
Whether it’s an autosomal test, a Y-DNA test or an mtDNA test, virtually all providers use the same science. Some providers offer an ‘off the peg’ solution such as Ancestral Origins™ or AncestrybyDNA™, so if you’re interested in these you should shop around for the lowest price. Most providers offer a test that interprets and presents the results in a unique way, so if one of these catches your eye, look for examples of how the results are presented on their website before you buy.
