| Abstract: | 2,596 Aroras and 2,629 Khatris comprising six endogamous groups of the Punjabis have been studied for A1A2BO blood groups and secretion of ABO(H) group specific substances. The values of chi-square and the genetical difference (G2) among these groups do not show statistically significant differences in these groups regarding the genetical characters studied. There is a closer affinity between Beri and Bunjahi on the one hand and Uttaradhi and Dhakhandian on the other and also between Uttaradhi and Khukhran; Dhakhandian and Sareen show a great difference among themselves as well as with other groups. The comparison of ABO blood group distribution and secretor factor among the different populations of India show that the distribution is similar among the North Indians. |
