ABSTRACT
The Crow's index of opportunity for natural selection has been calculated for three endogamous subpopulations namely Arya Vysya, Thrivarnika and Kalinga Vysya of North Coastal Andhra Pradesh. The total index is in the order Arya Vysya > Thrivarnika > Kalinga Vysya. However, the mortality component is more in Kalinga Vysya, reflecting the poor medical facilities available to them due to their low socio- economic profile compared to other two populations. The results of the present study are compared with those among the other caste populations of Andhra Pradesh.
ABSTRACT
Opportunity for natural selection has been studied among the women of Kshatriya caste population from rural and urban areas of north coastal Andhra Pradesh. The urbanrural difference for different demographic characteristics is not significant. The contribution of fertility component for both Crow's index and Jonston and Kensinger's index is more. The present study is compared with other Andhra populations. The decreased mortality differentials in Kshatriyas suggest that this component was directly affected by the better socio-economic level and reflects on the population's transitional phase.
ABSTRACT
Data on two blood group and three serum protein polymorphisms of the Turpu Kapu, an endogamous population of Vizianagaram District, Andhra Pradesh (AP) is presented. The gene frequencies for the blood group systems ABO and Rh are within the ranges of distribution reported earlier among the caste populations of Andhra Pradesh. The study population shows highest frequency of Hp1 allele and the lowest frequency of Hp2 allele compared to the other populations of AP. The Cp system is monomorphic, all individuals being the BB type. The GC system exhibits polymorphism with the gene frequencies of GC1 and GC2 alleles showing the highest and lowest frequencies, respectively, as compared to the caste populations reported earlier. The c2 test suggest that this population is in Hardy-Weinberg Equilibrium.
ABSTRACT
A total of 76 individuals belonging to Sishta Karanam population, Andhra Pradesh, were tested for polymorphism in ABO and Rh (D) blood groups, two serum proteins, Haptoglobin and Ceruloplasmin, and one red cell enzyme, Glyoxalase-I. All the systems except Caeruloplasmin showed polymorphism. The frequency of AB phenotype is found to be highest in the Sishta Karanam when compared to the other caste populations of Andhra Pradesh so far studied. It was observed that the ABO system was not in Hardy-Weinberg Equillibrium. The Hp1-1 phenotype was absent in this population. The Glyoxalase-I locus showed all the 3 phenotypes.
