But what exactly is an autosomal DNA test, and how does it work?
Autosomal DNA is the genetic material that is inherited from both parents and is passed down through generations Unlike Y-DNA and mitochondrial DNA tests, which focus on specific ancestral lines, autosomal DNA tests provide a broader picture of one’s genetic ancestry by examining all 22 pairs of autosomes, or non-sex chromosomes This means that autosomal DNA tests can provide information about your ancestors from both maternal and paternal lines, giving you a more comprehensive view of your genetic heritage.
