Human Y-chromosome DNA haplogroup

Copied from Wikipedia, the free encyclopedia

 

 

In human genetics, a Human Y-chromosome DNA haplogroup is a haplogroup defined by differences in the non-recombining portions of DNA from the Y chromosome (called Y-DNA).

The Y chromosome consortium has established a system of defining Y-DNA haplogroups by letters A through to T, with further subdivisions using numbers and lower case letters.

Y-chromosomal Adam is the name given by researchers to a theoretical male who is the most recent common patrilineal (male-lineage) ancestor of all living humans. Estimations of the date of this common ancestor have varied significantly in different studies. He probably lived between 90,000 and 60,000 years ago in the African continent and is the male counterpart of Mitochondrial Eve, although he probably lived later than she did, possibly 50,000 to 80,000 years later.
