GENETIC DISTANCE AMONG FOUR COMMUNITIES AS BASED UPON ABO, Rh AND SECRETOR FACTOR

The present study has been carried out on 600 individuals of both the sexes from four endogamous castes i.e. Baniya, Brahmin, Khatri and Arora of Patiala City. A trend B>A>O>AB has been observed in all the four castes espect in the case of Brahmins where the trend is B>A>AB>O. The frequency of Rh-ves varies between 1.33% to 5.33% in the castes under study. Sectors have a greater sway over non-secretors in the four castes. The values of chi-squuare show significant differences between brahimins and Khatris and between Brahmins and Aroras whereas in other caste group combinations the values of chi-square are showing insignificant differences. The values of genetical distance between various caste combinations ranges between 0.546 to 0.582.
