Haplogroup E1b1a (Y-DNA)

Haplogroup E1b1a (Y-DNA)

In human genetics, Haplogroup E-V38 is a human Y-chromosome DNA haplogroup. It is the phylogenetic term for the series of unique sequence variants on the human Y-chromosome. It is often found in African males and their descendants and is heritably passed in lineage from father to son. Geneticists study these variants in populations to find the evolutionary lineage to a common male human ancestor. From 2002 to 2008, it was known as Haplogroup E3a. It can also be referred to in mutational nomenclature as E-V38.

E1b1a is the primary subclade of E in West Africans and many populations of Central, Eastern, and Southern Africa. It is observed in lower frequencies in North Africa,the Iberian Peninsula and parts of West Asia. E1b1a has several subclades but many members of E1b1a subclades are either E1b1a1a1f (E-L485) or E1b1a1a1g (E-U175).
