I viewed and now recommend Jonny Perl’s Legacy Family Tree Webinars presentation Beginning with DNA Painter from Wednesday. It’s extremely clear. Perhaps the chromosome mapping section gets deeper than some of us will want.
DNA Painter, which has a free tier, has had upgrades since I last looked at it, and there are more coming all the time. The video may only be free until next Wednesday. Take a look and follow Jonny’s recommendation of taking things slowly.
Note that Jonny is one of several DNA marquee speakers at the 2024 OGS Conference in Toronto.
