Seven genetic systems were used to investigate the racial composition of a sample from a low‐income Mexico City Mestizo group, finding estimates of 0.590, 0.348, and 0.062 of Indian, White, and Black ancestry, respectively. The results are similar to another Mexico City group studied previously and to several Mestizo populations from different parts of the country. The one thing in common in all these groups is low socioeconomic status. There is only one report suggesting that Mexico City… 

Admixture analysis of a rural population of the state of Guerrero, Mexico.

TLDR
The results show that the population of Tlapa in Guerrero, Mexico, has experienced little admixture with Europeans and/or West Africans and that heterogeneity is a major characteristic of Mexican populations and should not be disregarded when designing epidemiological studies of Mexican and Mexican American populations.

Gene Admixture in the Costa Rican Population

TLDR
It has been concluded that the Costa Rican population is truly trihybrid, similar to populations in other Latin American countries; however, it differs from them fundamentally by the proportion of gene flow from ancestral populations.

A Geometric Morphometric Study of Regional Craniofacial Variation in Mexico

Spanish speaking populations in the USA have long been categorised under the umbrella term ‘Hispanic’, which is a cultural construct. The term Hispanic ignores the unique ethnohistories and

Admixture in Mexico City: implications for admixture mapping of Type 2 diabetes genetic risk factors

TLDR
This work characterized the admixture proportions in a sample of 286 unrelated T2D patients and 275 controls from Mexico City and discussed the implications of the results for admixture mapping studies.

mtDNA affinities of the peoples of North-Central Mexico.

TLDR
Diagnostic, discrete character, molecular genetic evidence is provided that is informative with regard to both the magnitude of African admixture and the relative maternal contribution of African, European, and Native American peoples to the genetic heritage of Mexico.

Large scale mitochondrial sequencing in Mexican Americans suggests a reappraisal of Native American origins

TLDR
The results suggest that Native American founders diverged from their Siberian-Asian progenitors sometime during the last glacial maximum (LGM) and expanded into America soon after the LGM peak (~20-16 kya), support the pre-Clovis occupation of the New World.

Exchanging fluidsThe sociocultural implications of microbial, cultural, and ethnic admixture in Latin America

TLDR
The historical implications of functional (de facto) polygyny, sex-biased admixture, and assortative mating in Latin America are discussed, proposing that these three evolutionary mechanisms influenced mating patterns, shaping the genetic and cultural landscape across Latin America and the Caribbean.

OEIS complex: Prevalence, clinical, and epidemiologic findings in a multicenter Mexican birth defects surveillance program.

TLDR
Although twin zygosity was not defined, the observed severest phenotypes in twins endorse the hypothesis that OEIS and monozygotic twinning are features of disturbances on early blastogenesis.

Gene frequencies and admixture estimates in a Mexico City population.

TLDR
The present study reveals a higher proportion of Indian genes in the Mexico City population than estimated in previous publications.

Gene frequencies and admixture estimates in four Mexican urban centers.

TLDR
The general pattern has high Indian ancestry followed by white and black ancestry, congruent with most other studies performed in Mexico, including the east coast, where Indian ancestry predominates despite a clear increase in the black contribution.

Gene frequencies and admixture estimates in the state of Puebla, Mexico.

TLDR
The results show that the proportions of black, indian, and white genes are 10.7%, 56.3%, and 33.0%, respectively, in a trihybrid model, which indicates that the black ancestry may be artifically high.

Genetic distances for ABO and Rh(D) blood groups in the state of Nuevo León, Mexico.

TLDR
The populations thought descended from the immigrants that colonized northeastern Mexico four centuries ago were shown to have received a high genetic contribution from Spanish, a lesser contribution from French, German and Portuguese, and a low contribution from Western Europeans.

Human biology in Mexico. II. A comparison of blood group, serum and red cell enzyme frequencies, and genetic distances of the Indian populations of Mexico.

TLDR
Three different genetic distance measures suggest that the Mestizo population is a triracial hybrid, while the Indian population is closely related to its two most proximal geographic neighbors, Vera Cruz and Puebla.

Distribution of gene frequencies and discrimination probabilities for 22 human blood genetic systems in four racial groups.

TLDR
The combined new technology for blood grouping and electrophoresis using cellulose acetate membranes provides a powerful individualizing and discriminating tool for forensic science investigation.

Type II diabetes and its complications in Mexican Americans.

TLDR
A major opportunity--and challenge--exists to reduce substantially the morbidity, mortality, and economic burden associated with type II diabetes and its complications in the Mexican American population.

Group-specific component: evidence for two subtypes of the Gc1 gene.

A new method based on isofocusing electrophoresis in the study of the Gc (group-specific component) polymorphism, revealed differing electrophoretic patterns. These patterns can be explained by the

TLDR
The results show that susceptibility to DM and IGT is high in the population and are among the highest in the world.

The natural history of impaired glucose tolerance in the Pima Indians.

TLDR
It is concluded that in this population approximately one fourth of subjects with impaired glucose tolerance have NIDDM at five years and two thirds at 10 years (approximately one third revert to normal) and that age and plasma glucose and insulin levels are the best predictors of clinical outcome.
