Gene Admixture in the Costa Rican Population

Annals of Human Genetics, 2003
SummaryThe general population of Costa Rica has sometimes been considered to be the product of an amalgamation of groups of diverse origin. To determine the magnitude of accumulated admixture since Spanish colonization, 11 classic genetic markers were analyzed in a total of 2196 individuals originating from five distinct regions of the country.

Admixture, Population Structure, and F-Statistics [PDF]

Genetics, 2015
Abstract Many questions about human genetic history can be addressed by examining the patterns of shared genetic variation between sets of populations. A useful methodological framework for this purpose is F-statistics that measure shared genetic drift between sets of two, three, and four populations and can be used to test simple and ...

The geometry of admixture in population genetics: the blessing of dimensionality

GENETICS, 2023
Abstract We present a geometry-based interpretation of the f-statistics framework, commonly used in population genetics to estimate phylogenetic relationships from genomic data. The focus is on the determination of the mixing coefficients in population admixture events subject to post-admixture drift.

Genome-wide analysis of unrecognised ethnic group Chuanqing people revealing a close affinity with Southern Han Chinese

Annals of Human Biology, 2020
Background Chuanqing is an unrecognised ethnic group in Guizhou, southwest China. The genetic history of the Chuanqing people is hotly debated due to a lack of available genetic data.

Population admixture modulates risk for alcohol dependence [PDF]

Human Genetics, 2009
The admixture of different ancestral populations in America may have important implications for the risk for psychiatric disorders, as it appears to have for other medical disorders. The present study investigated the role of population admixture in risk for several psychiatric disorders in European-Americans (EAs) and African-Americans (AAs).

European and Polynesian admixture in the Norfolk Island population [PDF]

Heredity, 2009
The Norfolk Island population in the South Pacific is primarily the product of recent admixture between a small number of British male and Polynesian female founders. We identified and genotyped 128 Ancestry Informative Markers (AIMs) spread across the autosomes, X/Y chromosomes and mitochondrial DNA genome, to explore and quantify the current levels ...

Exploring genetic diversity in genome-wide association studies and polygenic risk scores in the admixed Brazilian population [PDF]

Genetics and Molecular Biology
The Brazilian population has a complex genetic background resulting from admixture of Native American, African, and European ancestries. This review examines how such diversity influences the findings of genome-wide association studies and the ...

Recent Admixture in an Indian Population of African Ancestry [PDF]

The American Journal of Human Genetics, 2011
Identification and study of genetic variation in recently admixed populations not only provides insight into historical population events but also is a powerful approach for mapping disease loci. We studied a population (OG-W-IP) that is of African-Indian origin and has resided in the western part of India for 500 years; members of this population are ...

Admixture estimates for the population of Havana City

Annals of Human Biology, 2009
The Cuban population is essentially a result of the admixture between Spanish, West African and, to a lesser degree, Amerindian tribes that inhabited the island.The study analysed the genetic structure of the three principal ethnic groups from Havana City, and the contribution of parental populations to its genetic pool.According to genealogical ...
