Human genetics

Human genetics describes the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics,...

, Haplogroup E1b (P177) is a human Y-chromosome DNA haplogroup.

Haplogroup E1b, along with haplogroup E1a

Haplogroup E1a (Y-DNA)

In human genetics, Haplogroup E1a is a human Y-chromosome DNA haplogroup. Haplogroup E1a, along with haplogroup E1b, is one of the two main branches of the older E1. The E1a clade is divided into several subclades.- Distribution :...

Haplogroup E1 (Y-DNA)

In human genetics, Haplogroup E1 is a human Y-chromosome DNA haplogroup. Haplogroup E1, along with haplogroup E2, is one of the two main branches of the older Haplogroup E. The E1 clade is divided into two subclades: E1a & E1b.- External links :*...

. So far there are no attested exempliars of E1b*. The clade is dominated by subclade E1b1 (E-P2 or E-PN2), which is by far the most frequent. Another subclade of E1b, E1b2 (P75), was announced in Hammer et al. (2003) and confirmed as a sibling to E1b1 in Karafet et al. (2008).

Tree

This phylogenetic tree of haplogroup subclades is based on the YCC 2008 tree and subsequent published research.

    Haplogroup E1b1 (Y-DNA)
    In human genetics, Haplogroup E1b1 is a human Y-chromosome DNA haplogroup.-Origin:E1b1 is likely to have originated in the highlands of East Africa's Ethiopia, as this is the place with the high frequency of ancestral subclades of this haplogroup. E1b1 is the ancestor of the majority of E...
