X‐chromosomal genetic diversity and linkage disequilibrium patterns in Amerindians and non‐Amerindian populations
Objectives: We report X‐chromosomal linkage disequilibrium (LD) patterns in Amerindian (Kogi, Wayuu, and Zenu) and admixed Latin American (Central Valley of Costa Rica and Southern Brazilian Gaucho) populations. Methods: Short tandem repeats (STRs) widespread along the X‐chromosome were investigated in 132 and 124 chromosomes sampled from the Amerindian tribes and the admixed Latin American populations, respectively. Diversity indexes (gene diver…
Niger‐Congo speaking populations and the formation of the Brazilian gene pool
We analyzed sequence variation in the mitochondrial DNA (mtDNA) hypervariable segment I (HVS‐I) from 201 Black individuals from two Brazilian cities (Rio de Janeiro and Porto Alegre), and compared these data with published information from 21 African populations. A subset of 187 males of the sample was also characterized for 30 Y‐chromosome biallelic polymorphisms, and the data were compared with those from 48 African populations. The mtDNA data …
MtDNA Haplogroup Analysis of Black Brazilian and Sub-Saharan Populations
Seventy individuals from two African and four black Brazilian populations were studied for the first hypervariable segment of mtDNA. To delineate a more complete phylogeographic scenario of the African mtDNA haplogroups in Brazil and to provide additional information on the nature of the Atlantic slave trade, we analyzed our data together with previously published data. The results indicate different sources of African slaves for the four major B…
Demographic and evolutionary trajectories of the Guarani and Kaingang natives of Brazil
A total of 278 individuals from two Brazilian Indian tribes (Guarani and Kaingang) living in five different localities had their mitochondrial DNA sequenced for the first hypervariable segment (HVS-I), and a fraction of them was also studied for seven biallelic Y-chromosome polymorphisms. Nineteen HVS-I lineages were detected, which showed distinct distributions in the two tribes. The G ST value obtained with the mtDNA data is about 5 times highe…
Heterogeneity of the genome ancestry of individuals classified as White in the State of Rio Grande do Sul, Brazil
One hundred nineteen individuals classified as White, living in different localities of the Brazilian state of Rio Grande do Sul, were studied in relation to the HVS-I region of the mitochondrial DNA (mtDNA). The male fraction of the sample (N = 74) was also tested for seven Y-chromosome polymorphisms. In a specific population (Veranópolis), a city characterized by a large influence of the Italian immigration of the 19th century, the results from…
