About DNA Testing and What it Offers

While DNA testing won’t always provide the answers that adoptees are looking for, it can help you trace your biological roots in ways that no other resources can. There are 3 main types of DNA testing: Y-DNA, mtDNA, and autosomal DNA analysis. The best DNA test to take for finding your birth parents or other close biological relatives is an autosomal DNA test.

Autosomal DNA and DNA with Shared Relatives
Autosomal DNA testing analyses the autosomes in your cells. Autosomes are chromosomes that do not determine your gender but can influence numerous other genetic traits. Both men and women can take an autosomal DNA test. These tests can help you match with relatives up to 7 generations back on both your birth mother and birth father’s side.

Autosomal testing can offer you several DNA matches. Through these matches, you will be able to more easily trace your birth parents. It is important to choose an autosomal DNA testing service that will offer you both a high number of genetic matches as well as accuracy with close relative matches.

Your biological father and mother share DNA with their other relatives. Discovering who these relatives are can help you determine your parentage through shared match tracing.
