Webinar Description

Chromosome mapping is typically achieved by mapping the segments of DNA we share with an identified match. In this lecture, learn how to map segments of DNA that you DO NOT share with a match!

Really enjoyed this webinar and made immediate use of approach with a sibling & 1C1R. However got myself really confused about use of a parent's data. How does a parent's DNA apply to this approach?
