Abo Blood Group Distribution and Gene Frequencies of Telangana People

This study examined the distribution of ABO and Rh blood groups among college students in Telangana, India. B +ve was the most prevalent blood group, followed by O+ve, with Rh-positive samples predominating (9.0% Rh-negative). A-ve and B-ve groups were equally represented, while AB-ve was rare. Compared to historical data, A+ve and A-ve groups have declined. The prevalence of O blood groups is increasing, with its overall frequency approaching that of B blood groups, suggesting a potential shift towards O group dominance. These results indicate a change in ABO blood group distribution in Telangana, possibly due to selective marriages between heterozygous B and Oalleles.
