My DNA Answers to Common Questions

My name is Richard Hill and DNA Testing is my web site.

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 new section and content will build steadily over time…so check back periodically.

You can also subscribe to my blog through the box at the left. Just choose your preferred RSS reader and you will know when I  add new pages anywhere on this site.
