This DNA Answers section provides a growing list of frequently asked questions about DNA testing and my answers to those questions. It’s essentially a DNA FAQ.
I get DNA questions from adoptees, genealogists, and a surprising number of other people who are uncertain of their biological relationship to a parent, sibling, or other person.
Often, DNA testing can provide the missing piece to whatever mystery is puzzling you.
This is a growing section and content will build steadily over time…so check back periodically.
