You’ll also find differences in how long processing takes, as well as in each company’s privacy policy.We took the specific elements into consideration while evaluating each DNA service’s test:Looking for something else that didn’t make our top picks? Not only is there the potential to discover distant relatives, you’ll see how they actually fit into your family tree. 23andMe offers the most well-rounded, comprehensive at-home DNA health test on the market. The company was also prohibited from shipping DNA kits to Maryland.The 23andMe shipping issues resulted partly because when the company first launched, it tested for a litany of health issues and genetic markers for disease, raising concerns from the FDA and other agencies. So for the one-time fee of $99 you can expect to see your results become more accurate as the years go on.Its biggest shortcoming is that it costs the same price as 23andMe but only tests autosomes instead of also testing mtDNA and yDNA. If you’ve read all the DNA test reviews, and are still confused, read on. A perfect match means you are related, but you might be 48th cousins!The only company to offer individual mtDNA kits is The 23rd human chromosome has two versions, the X and the Y.Women have two X-chromosomes, while men have one X and one Y.Y-DNA testing kits examine only the Y-chromosome, therefore only males can take this test. It’s also a great ancestry test if you think you have With three tests to choose from, how do you decide which is best for you?For most people, the atDNA test is the clear winner, and it is the one test that every testing company offers.Because your atDNA comes from all of your ancestors, this test is good for finding a range of ancestors and living relatives.It can also provide you with reasonable estimates of the ethnicity of your ancestors, or the regions of the world where they lived.The main drawback to atDNA is that it gets so jumbled together after a few generations that it becomes unreliable the further you try to go back.Most of the time, an atDNA test is only useful for about 6-8 generations.atDNA can provide some great leads on finding others who are researching the same family tree as you.Because mtDNA comes to you only from your mother, and from her mother, it only helps you trace one line.You can use it to prove a common ancestor with someone else, but only in a direct maternal line.It can, however, trace that line back a very long way – sometimes 10,000 years or more.That can provide evidence that your mother’s maternal line came from a very specific region or ethnicity.But it is less useful when finding living relatives.The Y-DNA test is sort of like the mtDNA test, but it follows a direct paternal line instead.That means a Y-DNA test can tell you about your father’s father’s father’s father, and many generations before that, but not about any of your other ancestors.Y-DNA is most useful if you want to prove a connection to a certain ancestor.Say that you have a common surname, like Smith, and want to know if you are related to someone else named Smith.A Y-DNA can prove (or disprove) that the two of you are related.Like the mtDNA test, Y-DNA may let you trace a line back for dozens of generations.It can also tell you the ethnicity or region of origin of your paternal line.One major drawback to Y-DNA is that only males have Y-DNA, so only males can take the test.However, a woman can still find Y-DNA results by having a close male relative take it for her, such as her brother, father, paternal uncle, or cousin by a paternal uncle (but not her son, since he got his Y-chromosome from his paternal line, not hers).In the same way, you can trace other paternal lines by asking an appropriate family member to take the test and share the results with you.All three of the tests can provide you with information on where your ancestors lived.But the information they provide varies from test to test.The companies that provide DNA testing divide the world up into regions in different ways.
