centimorgan

The results show the number of genome locations that match, with each match called a centimorgan.

Jenny searched for answers online and learned about the centimorgan - a unit of genetic linkage.

Sachetta and the woman shared a centimorgan count of between 80 and 90, which was less than 1 percent shared DNA between the two of them.

In genetics, a centimorgan is a unit for measuring genetic linkage.

To put that number in perspective, the centimorgan count shared by Sachetta and his own son, Gabe, is 3,439.
