Y-chromosomal Status of Six Indo-European-speaking Arab Subpopulations in Chaharmahal and Bakhtiari Province, Iran.

Background: We analyzed the Y-chromosome haplogroups of six documented Arab subpopulations that accommodated separately in different counties of Chaharmahal and Bakhtiari Province but nowadays speak Indo-European language (Luri and Farsi).

Methods: This was an outcome study conducted in 2015 to test whether there was any genetic relatedness among some Indo-European-speaking Arab subpopulation accommodated in a geographically similar region, Chaharmahal and Bakhtiari Province, Iran. Seven main Y-chromosome bi-allelic markers were genotyped in six documented Arab subpopulations.
