Genetic Ancestor

Because the term “ancestor” is used in genetic genealogy, here is some clarification as to what that term means. A haplogroup refers to people in a family of lineages that share a common ancestor. So for other people who share my haplogroup the term is an indicator of whether we share a genetic ancestor. However, this does not tell me whether I am closely related to that person with whom we share a haplogroup.

The Most Recent Common Ancestor

The time of The Most Recent Common Ancestor(TMRCA) refers to “the most recent individual from which all the people in the haplogroup are directly descended.” Strictly speaking, it does not mean I am directly related to TMRCA in my haplogroup. It means that I have a common ancestor in my haplogroup dating back thousands of years.
