Abstract
Restriction endonuclease analysis was used to test a proposed genetic model using .alpha.-globin gene number to account for the observed distributions of the proportions of HbS in sickle cell trait. In a subsample of specimens collected during a population survey in India, these studies confirmed that the postulated genotype was present in 22 of the 23 individuals examined. In the study population, the number of .alpha.-globin genes explains about 90% of the variance in the proportion of HbS in sickle cell trait (r2 = 0.895, P < 10-10).
