What is Phasing on GEDMatch?
Phasing is dividing your DNA information into paternal and maternal chromosomes. You must have a DNA kit for yourself and at least one parent for the process to work. Your phased kit will help you filter your DNA matches on GEDMatch to determine which DNA segments came from individual grandparents, great-grandparents, and so on.

In this video, I show you the difference between a phased DNA kit and an unphased DNA kit.
A phased kit can reduce false matches. Sometimes your DNA matches will share DNA with me. If they don’t share DNA with my parents, then that is a false match. You want to discard those matches from your research list.
Once you have eliminated false matches from your research possibilities, then you can dig deeper. Now you can pinpoint whether your matches align with your mother’s and father’s lines. How cool is that?
