Comparative genomics of indels in primate lineages and the possible effect of the MET promoter indel on gene expression
(2016)
Approximately six million years ago, the human and chimpanzee lineages diverged from a common ancestor resulting in two distinct species with a great number of different morphological, behavioral, cognitive and other ...
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 ...
Relación entre los principales linajes Indígenas del ADN Mitocondrial en las Islas de Puerto Rico y República Dominicana
(2014)
It is well known that indigenous mitochondrial haplogroups A and C are predominant in the Dominican Republic and Puerto Rico. Medium networks built of sequences of the hypervariable regions of mtDNA have identified 13 ...
Tracing maternal Amerindian ancestry in the Aruban population through mtDNA sequencing
(2011)
As part of a study about pre-Colombian female migrations in the Caribbean, the mitochondrial DNA of the modern Aruban population was studied. The main objective was to identify the haplotypes in the Amerindian haplogroups ...
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 ...
Polymorphisms influencing the shovel-shaped incisors phenotype in Puerto Rico
(2017)
Puerto Ricans phenotypic traits are a combination of the admixture of their ancestors Taínos with Europeans and Africans. Shovel-shaped incisors are a common trait among Taínos’ skeletons and are still present in the Puerto ...
Mitochondrial phylogeny of Sphaerodactylus species endemic to islands in the Mona Passage and its biogeographical implications
(2011)
Little is known about the natural history of the Sphaerodactylus species endemic to the three islands located in the Mona Passage, mostly because of the logistics of getting to the islands and because of the cryptic behavior ...
Genetic Variation in the African Mitochondrial Haplogroup L3e in Puerto Rico
(2012)
This study aims to clarify the uncertainties of the African maternal origin of the Puerto Rico modern population that occurred during the slave trade. Haplogroup L3e was chosen for this study because it combines the ...
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 ...
No guts, no reef: Understanding the microbiome, genetic diversity, and phylogenetic relationships of the Puerto Rican long-spined black sea urchin, Diadema antillarum, a keystone species of the Caribbean reef
(2020-11-17)
In this paper we describe the gut microbiome of the Puerto Rican keystone sea urchin Diadema antillarum. We also used next generation sequencing of the cytochrome b region to examine the phylogenetic relationships among ...
