We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 112 Mexicans from the state of Morelos living in the city of Cuernavaca (N = 82) and rural communities (N = 30), to obtain information regarding allelic and haplotypic frequencies. The most frequent haplotypes in Morelos include seven Native American, one European, one African and one Asian haplotype. Admixture estimates revealed that the main genetic components in Morelos are Native American (60.43 ± 2.22% by ML; 53.57% of Native American haplotypes) and European (39.58 ± 3.70% by ML; 27.68% of European haplotypes), and a virtually absent African genetic component (0.00 ± 4.93% by ML; but 11.16% of African haplotypes).

我们通过基于PCR-SSP的方法研究了生活在Cuernavaca市的莫雷洛斯州的112名墨西哥人中的HLA I类（HLA-A，-B）和II类（HLA-DRB1，-DQB1）等位基因（N = 82）和农村社区（N = 30），以获取有关等位基因和单倍型频率的信息。莫雷洛斯州最常见的单倍型包括七种美洲原住民，一种欧洲，一种非洲和一种亚洲单倍。混合物估计显示，莫雷洛斯州的主要遗传成分是美洲原住民（按ML分类为60.43±2.22％；美国原住民单倍型为53.57％）和欧洲（按ML分类为39.58±3.70％；欧洲单倍型为27.68％），以及几乎没有非洲人遗传成分（按ML计为0.00±4.93％;但为非洲单倍型的11.16％）。
