The Chromosome Browser — One-to-many is a graphical tool that allows you to better understand the relationship between you (or any of the people whose DNA kits you manage) and up to seven DNA matches. Together with family tree details like shared ancestral surnames and shared Smart Matches, you may be able to trace the common ancestors
who passed down shared DNA segments to you and your DNA Matches and reconstruct the exact relationship path between you and DNA Matches that intrigue you.
A chromosome browser is a tool that maps a person’s chromosomes graphically. Essentially it is used to visualize shared DNA segments that people who share DNA have in common. MyHeritage locates such shared segments when it analyzes your DNA results, and determines that you are a match with someone else when there are sufficient shared segments of sufficient size between you. Such shared segments are a probable indication that you and your match both inherited DNA from one or more common ancestors. By studying those shared segments and testing the DNA of additional relatives, it is possible to determine who the segments originated from and in turn, determine the relationship between the two people who have taken the DNA test.
The initial version of the MyHeritage Chromosome Browser displays DNA segments shared by you with one DNA Match and is found at the bottom of each DNA Match Review page. You can read more about that basic version in the following FAQ: What is the Chromosome Browser for shared DNA segments?
