I-M423 (Y-DNA)

This project is for people who have tested and been assigned the paternal haplogroup I2a1b (M423) and also for people who are believed to have belonged to this paternal haplogroup based on tests done on descendants.

Formerly: I2a2

Distribution

"Haplogroup I-M423 is the most frequent Y-chromosome Haplogroup I in Central and Eastern European populations, reaching its peak in the Western Balkans, most notably in Dalmatia (50-60% [1]%29 and Bosnia-Herzegovina (up to 71%,[17] avg. 40-50% [1]). A greater variance of this group has been found in Ireland and Great Britain, but overall frequency is very low (2-3%). Haplogroup I-M423 is virtually absent in Fennoscandia, Western and Southwestern Europe." (Wikipedia)
