For genealogical purposes, there are three main types of DNA tests that are available: Y-chromosome (Y-DNA) tests for the direct paternal line, mitochondrial DNA (mtDNA) tests for the direct maternal line, and autosomal DNA (atDNA) tests for finding matches on all your ancestral lines.
Have you ordered your first DNA test kit and are wondering what it will look like and how you will use it? Or are you considering doing a DNA test to help with your family research and want to learn more before you order - what's in the kit and how you physically take the test?
So, you've decided to test your DNA or that of another family member? Not sure how? Well, once you've decided who to test and selected the appropriate test type, ordering the test kit is quick and easy. Just follow these simple steps and your Family Tree DNA test kit will be ordered and on its way!
Family Tree DNA hosts a large number of DNA project groups for the benefit of its customers. Included are thousands of different surname projects, geographic projects, haplogroup-specific projects, lineage projects and private family projects.
Occasionally there are sales or discount voucher codes available for the purchase of DNA tests for genealogy. I will publish them on this page whenever I'm aware of good deals to share.
Once you start taking an interest in DNA testing for family history purposes, you will naturally want to find out more about how everything works - the test types, who to test, choice of testing companies, understanding results, taking it further, support groups, online forums, advanced tools, projects, etc.
Thousands of genealogists have tested their DNA for family history purposes, but from my experience it seems that many are not members of DNA Interest Groups (DIGs) or even family history societies - they are going it alone, or getting their support entirely online.
When you test your autosomal DNA, your X-DNA is also examined and included in your raw data &/or match results. When you match someone on your autosomal DNA and also share segments on the X-chromosome, the unique inheritance pattern of X-chromosomes can help isolate your common ancestor to particular lines of your ancestry.
Everyone inherits autosomal DNA from their parents: 50% from each parent, which contains a random mix of DNA segments from their parents, their parents, their parents, back for several more generations.
