Rhesus genotype frequency in Bangladeshi population.

The prevalence of Rhesus genotypes in Bangladesh has been studied and several important findings were observed. This being the initial report, includes a population of 1600 only. By using five Rh antisera (Anti-C, Anti-D, Anti-E, Anti-c and Anti-e) a genotype can be deduced since anti-d is not available. More often only a probable genotype can be suggested after reference to the known chromosome frequencies in the population. By using family studies in conjunction, it may be possible to determine genotype with certainty. The prominent Rhesus genotype was CDe/cDE (R1R2), i.e., 39.75%, Rhesus genotype cde/cde (rr) was found to be only 1.75%. The genotype cdE/cde (r"r) was not detected in the present series of Bangladeshi population. These results have been compared with the English and the Indian Bengalee Hindu Population.
