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! Using close relatives such as parents or siblings we can figure out where pieces of DNA came from based on lack of sharing.
