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.
几组南美印第安人中纯合 HLA 单倍型的人数比假设平衡未改变时预期的人数少 39%。在一个由 122 人组成的亚群体中,其父母的 HLA 构成已知,纯合子人数比预期少 56%。这种不足在不同的单倍型和不同的部落群体中广泛分布。
