How does DNA help you find relatives?
3 types of DNA hold clues to your family connections
DNA is a powerful way to connect family members. When the paper trail ends, DNA can provide strong leads for finding missing relatives and filling in gaps in your family tree.
3 types of DNA markers are accepted for searching: Autosomal DNA, Y-DNA, and mtDNA.
Each DNA marker type has its own specific purpose and differs greatly in the type of information that it will provide you.
