Mayan Genetics
The relationship of the Mayas to other indigenous peoples of the Americas has been assessed using traditional genetic markers. Mayas inhabited several parts of Mexico and Central America, including Chiapas, the northern lowlands of the Yucatán Peninsula, the southern lowlands and highlands of Guatemala, Belize, and parts of western El Salvador and Honduras. Genetic studies of the Maya people are reported to show higher levels of variation when compared to other groups.
Maya intra-population variation has been examined by means of the following tests: Human leukocyte antigen (HLA) polymorphisms, polymorphic Alu insertions, mitochondrial DNA (mtDNA), and Y chromosome data. The results indicate that ancestors of the Mayas made a finite number of entries into the Americas over the Bering land bridge.〔
==Human leukocyte antigen polymorphisms==
In a study conducted by Michael H. Crawford, human leukocyte antigen loci were found to encode for major histocompatibility complexes.〔 Allele frequencies were plotted for similarities using principal component analysis (PCA) for the HLA-A locus exhibited by the Mayan population. Results plot close similarities with the Inupiat people of Native Alaskan heritage, the Waiapi of central Brazil and the Tohono O'odham of northern Mexico.〔 The HLA-B locus was examined in a PCA plot and indicates a proximity to the Zuni of southwest North America and the Aymara of southern South America.〔
