Genetic Admixture and Distances Between Populations from Monterrey, Nuevo Leon, Mexico, and Their Putative Ancestral Populations

The allele frequencies of the ABO, Rh, MNSs, Duffy, P, Kidd and Lutheran blood group systems within populations from the Monterrey Metropolitan area (MMA) México, grouped in accordance with the grandparent's place of birth, were ascertained along with those from the populations thought to have...

Description
Summary:The allele frequencies of the ABO, Rh, MNSs, Duffy, P, Kidd and Lutheran blood group systems within populations from the Monterrey Metropolitan area (MMA) México, grouped in accordance with the grandparent's place of birth, were ascertained along with those from the populations thought to have contributed to their genetic constitution, i.e., native Indians, Western Europeans (Spanish, Portuguese, French and German), Sephardic Jews and Africans. Genetic admixture and distances were estimated, and three dimensional diagrams are presented. It is found that the gene frequencies of the populations in MMA are intermediate to those in the putative ancestrals, indicating that they are Mestizo but with a genetic structure different from that of the Mestizo populations from Central México, but similar to the Mexican-American population from South Texas. The populations from MMA have had a predominant influence from the Spanish; other important contributors have been the French, German and Portuguese, and to a lesser degree Sephardic Jews. There is almost no influence from Africans. The greater the number of grandparents that were born in Nuevo León or in zones I or II (Northeastern México) the greater the European influence; the latter decreases when the number of grandparents that were born in Nuevo León are fewer or when they were born in the zones of Central or South México, where there has been a greater influence from the native Indians.
