What is the Difference Between Family Tree DNA and Ancestry DNA?

Family Tree DNA and AncestryDNA are both popular companies offering direct-to-consumer DNA testing services. They have some similarities, such as cousin matching, family tree building, and ethnicity estimates. However, there are key differences between the two:

1. DNA Testing Types: Family Tree DNA offers specific Y-DNA and mtDNA tests, which provide information about paternal and maternal lines, respectively. AncestryDNA only offers autosomal testing, which provides information about both parents' ancestry.
2. Haplogroup Results: Family Tree DNA includes haplogroup results in their Y-DNA testing, which offers better insight into more distant ancestry. AncestryDNA does not provide haplogroup results.
3. Database Size: AncestryDNA has a larger database of over 25 million users, while Family Tree DNA has a smaller user base. However, Family Tree DNA has a better international database, which may be more helpful for people with recent immigrant ancestors.
4. Ethnicity Estimates: The ethnicity estimates provided by the two companies may differ due to their different reference populations and algorithms.

Ultimately, the choice between Family Tree DNA and AncestryDNA depends on your specific goals and interests. If you are looking for more information about your paternal or maternal lines, Family Tree DNA may be a better choice. On the other hand, if you are interested in a larger database and more resources for genealogy research, AncestryDNA might be more suitable.
