Procedencia del ADN mitocondrial euroasiático occidental en Puerto Rico
(2009)
This study analyzed 102 mtDNA control region sequences with the objective of classifying them into sub-haplogroups and estimating their continental origin. Principal component analysis of the western Eurasian sub-haplogroups ...
Genetic diversity of the shiny Cowbird (Molothrus bonariensis minimus): A mtDNA study on the variability within original and expanded range
(2006)
The geographic range of the Shiny Cowbird (Molothrus bonariensis minimus) was limited to
northeastern South America until the twentieth century. However, this range has expanded to the
Caribbean and more recently to the ...
The origins of the African ancestry in the Puerto Rican population according to restriction analysis of the mitochondrial DNA
(2006)
The matrilineal genetic composition of 79 Puerto Rican samples with proven Sub-Saharan
African ancestry was examined by restriction fragment length polymorphism (RFLP) analysis.
The resulting data were combined with ...
Haplogroup frequencies of Y chromosomes with the 92R7T allele in Puerto Rico.
(2007)
For over two decades, Y chromosome polymorphisms have successfully
been used as lineage markers in evolutionary studies to determine human origins,
migrations waves, and admixture. Determining the frequency and ...
Genetic prints of Amerindian female migrations through the Caribbean revealed by control sequences from Dominican haplogroup a mitochondrial DNAs.
(2006)
Both historical literature and popular opinion tend to establish that the
population of the Dominican Republic descended mainly from Africans and
Europeans. Amerindian ancestry was considered negligible due to Taíno ...
In search of pre-columbian migrations to the Caribbean: indigenous mitochondrial DNA from Northern South America
(2009)
In an effort to gain a better understanding of the migratory processes related to the peopling of the Caribbean, the aim was to characterize Native American mtDNAs from Colombia and Venezuela and compare them to their ...
