DNA Comparison Tool

From ISOGG Wiki

"DNA Comparison Tool" is a feature of 23andMe's Personal Genome Service. It can be accessed under My Results/Ancestry Tools in the 23andMe user interface or here.

This lab compares 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. The threshold for matching segments is five Centimorgans, in contrast to the 7 cM threshold for DNA Relatives. Therefore, it is possible to discover potential relatives not included in the DNA Relatives feature.
