Regional and genetic variations among the Hindu Gujjars of Northwestern India

Serogenetic investigations among the Hindu Gujjars of Ropar District in Punjab were carried out with special reference to their genetic relationship with populations of other localities. Hindu Gujjars of Northwestern India show intragroup genetic variations, significant especially at the ABO locus. The magnitude of intragroup diversity varies depending upon the physical distance between the two groups. The plausible explanation for their diversity seems to be the founder effect, genetic drift and, their breeding and geographic isolation.
