DNA Comparison Feature
From ISOGG Wiki
The 'DNA Comparison Feature is a tool provided by 23andMe as part of their Personal Genome Service. It can be accessed under Family and Friends/Advanced DNA Comparison in the 23andMe user interface or via this link when logged in.
The tool compares the participant's DNA bit by bit to see which segments are shared with close and distant family. It examines DNA Relatives matches in more detail, displaying where DNA segments start and end and how DNA is transmitted across multiple generations by comparing multiple family members against a person in question.
