I couldn't help but reply with all this amateurism, uneducated people. It's not confusing at all, it's very simple, read this..Here are the different sub-clades:
E1b1b1a1b
E1b1b1a1b V32
The E1b1b1a1b (V32) subclade is a descendant of E1b1b1a1 (V12).
E1b1b1a1b/V32 is highest in Somalia (47-75%), Sudan (52%) and Ethiopia (40%). All these chromosomes detected to date fall into the East African M78 g microsatellite cluster, which is associated with Cushitic (Afro-Asiatic) language groups in Somalia, Ethiopia and Kenya. There is some notion that the Great Rift Valley acted as a barrier to isolate language and genetic groups in this region. This subclade is abundant in Somalia, although the STR diversity is rather low. This data would suggest that the E1b1b1a1b/V32 Somali population was shaped by a founder effect, somewhat recently. The E1b1b1a1b/V32 was not found in Turkish population with M78 g microsatellite cluster, indicating that there is not a perfect correspondence between the M78 g microsatellite cluster and the E1b1b1a1b/V32 subclade. The g cluster is characterized by a short and unique DYS19 allele (11 repeats), a situation in which it acts almost as a unique event polymorphism like a SNP. The estimates for the TMRCA of this subclade are approximately 4-8kya.
E1b1b1a2
E1b1b1a2 V13
E1b1b1a2 (V13) is highest in the Balkan Peninsula (Albania 32%, Greece 18-45%) and diminishes from here northward. It overlaps with the previously identified E1b1b1a M78 a cluster, and makes up the majority of E chromosome types in Europe. This cluster was found primarily in Europe and to a lesser extent the Near East (e.g. 5% Turkey). It is rarely found outside of Europe.
E1b1b1a1*
E1b1b1a1* V12
E1b1b1
a1* (V12) sh
ows the highest frequency in Northeast Africa (e.g. up to 44% in South Egypt and 19% in Sudan). It may have migrated from Egypt in the North, south to Sudan along the Nile River Valley. It is not present at levels >5% elsewhere, except ~6% in Basques from France. TMRCA estimates an origin at 14-15kya.
Good luck with grasping this stuff
