Studies on the Dd antigen-antibody system. II. Antigen Dd reactivity in some north indian populations.
The frequency of antigen Dd-reactors has been recorded in Muslims and Buddhists from Ladakh, in Rana Tharus from Uttar Pradesh and in two samples of largely Jat Sikh origin from Punjab, all in India. The results show a wide range of variation, from 0% in the Rana Tharus to 25% in the Punjabi blood donors, of incidence of antigen Dd-reactivity in these populations.
