Evidence for heterosis in the HLA system.

Abstract

The number of persons with homozygous HLA haplotypes in several groups of South American Indians was 39% less than that expected assuming unmodified equilibrium. In a subpopulation of 122 persons whose parents' HLA constitutions were known, there were 56% fewer homozygous persons than expected. This deficit was widely distributed in different haplotypes and different tribal groups.
