Abstract
Effect of consanguinity on the phenotypic and allelic frequencies of ABO blood groups in muslims of Purnia was studied. Nonconsanguineous population served as control. Distribution of ABO blood groups showed a predominance of blood group B and O. A trend of B > A > O> AB was observed in nonconsanguineous and O> B > A > AB in consanguineous populations, respectively. The alteration in phenotypic distribution indicates a trend of selection of recessive trait due to consaguinity.
