To estimate the maternal contribution of Native Americans to the human gene pool of Puerto Ricans--a population of mixed African, European, and Amerindian ancestry--the mtDNAs of two sample sets were screened for restriction fragment length polymorphisms (RFLPs) defining the four major Native American haplogroups. The sample set collected from people who claimed to have a maternal ancestor with Native American physiognomic traits had a statistically significant higher frequency of Native…

Reconstructing the population history of Puerto Rico by means of mtDNA phylogeographic analysis.
TLDR
HVR-I sequences of haplogroup U samples revealed a strong North African influence among West Eurasian mtDNAs and a new sub-Saharan African clade and a statistically significant negative correlation was observed between the Amerindian and African frequencies of the municipalities.
Mitochondrial DNA Analysis in Aruba: Strong Maternal Ancestry of Closely Related Amerindians and Implications for the Peopling of Northwestern Venezuela
TLDR
It is hypothesized that the frequency of haplogroup D mtDNAs should be high in the Caqueto tribe of coastal Falcon in Venezuela and at least moderate in the Guajiro Indians of eastern Colombia, and it is suggested that the native Aruban Indians contributed substantially to the current mtDNA pool of Arubans despite the repeated historical deportation events.

TLDR
It is hypothesized that the frequency of haplogroup D mtDNAs should be high in the Caquetı́o tribe of coastal Falcón in Venezuela and at least moderate in the Guajiro Indians of eastern Colombia, and that the native Aruban Indians contributed substantially to the current mtDNA pool of Arubans despite the repeated historical deportation events that presumably removed the complete populations from the island.
Ancient DNA reconstructs the genetic legacies of pre-contact Puerto Rico communities
TLDR
Three mtDNA haplotypes from pre-contact Puerto Rico persist among Puerto Ricans and other Caribbean islanders, indicating that present-day populations are reservoirs of pre- contact mtDNA diversity.

Genetic ancestry and indigenous heritage in a Native American descendant community in Bermuda.
TLDR
Analysis of genetic variation in 111 members of Bermuda's self-proclaimed St. David's Island Native Community reveals that the majority of mitochondrial DNA (mtDNA) and Y-chromosome haplotypes are of African and West Eurasian origin, unlike other English-speaking New World colonies.
Native American mtDNA prehistory in the American Southwest.
TLDR
The mtDNA diversity of the proposed descendants of the multiethnic Hohokam and Anasazi cultural traditions, as well as Uto-Aztecan and Southern-Athapaskan groups are examined to investigate hypothesized migrations associated with the Southwest region, finding no evidence of a movement of mtDNA lineages northward into the Southwest from Central Mexico.
Genetic origin, admixture, and asymmetry in maternal and paternal human lineages in Cuba
TLDR
The extensive process of population admixture in Cuba has left no trace of the paternal Native American lineages, mirroring the strong sexual bias in the admixture processes taking place during colonial times.
Genetic diversity in Puerto Rico and its implications for the peopling of the Island and the West Indies.
TLDR
To infer patterns of pre-Columbian and historic peopling of the Caribbean, genetic diversity in 326 individuals from the southeastern region of Puerto Rico and the island municipality of Vieques was characterized, attest to the distinct, yet equally complex, past for the male and female ancestors of modern day Puerto Ricans.
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.

mtDNA variation of aboriginal Siberians reveals distinct genetic affinities with Native Americans.
TLDR
The hypothesis that the first humans to move from Siberia to the Americas carried with them a limited number of founding mtDNAs is supported and that the initial migration occurred between 17,000-34,000 years before present.
mtDNA and Y-chromosome polymorphisms in four Native American populations from southern Mexico.
TLDR
This analysis suggests that certain Y-chromosome haplotypes were brought from Asia during the colonization of the Americas, and a differential gene flow was introduced into Native American populations from European males and females.
Asian affinities and continental radiation of the four founding Native American mtDNAs.
TLDR
Observations suggest that the process of tribalization began early in the history of the Amerinds, with relatively little intertribal genetic exchange occurring subsequently.
Heterogeneity of mitochondrial DNA haplotypes in Pre-Columbian Natives of the Amazon region.
TLDR
It is suggested that, in addition to the postulated bottleneck effect during the migration from Asia to the Americas, the depopulation effect started by European colonization in the 16th century contributed to the reduction in genetic variability of Amerindians.
mtDNA haplogroup X: An ancient link between Europe/Western Asia and North America?
TLDR
Time estimates for the arrival of X in North America are 12,000-36,000 years ago, thus supporting the conclusion that the peoples harboring haplogroup X were among the original founders of Native American populations.
Amerindian mitochondrial DNAs have rare Asian mutations at high frequencies, suggesting they derived from four primary maternal lineages.
TLDR
The analysis of mitochondrial DNA sequence variation of the South American Ticuna, the Central American Maya, and the North American Pima revealed that Amerindian populations have high frequencies of mtDNAs containing the rare Asian RFLP HincII morph 6, a rare HaeIII site gain, and a unique AluI site gain.
Distribution of mtDNA haplogroup X among Native North Americans.
TLDR
The low frequency of haplog groups other than A, B, C, D, and X among the samples studied suggests a paucity of both recent non-Native American maternal admixture in alleged fullblood Native Americans and mutations at the restriction sites that characterize the five haplogroups as well as the absence of additional (undiscovered) founding haploggroups.
Mitochondrial DNA diversity in the Kuna Amerinds of Panamá.
TLDR
The low mtDNA diversity of Kuna Amerinds, as opposed to the generally high levels of mtDNA variation detected in other Amerind groups, demonstrates the need for adequate sampling of cultural or racial groups when attempting to genetically characterize human populations.
The ancestry of Brazilian mtDNA lineages.
TLDR
The mtDNA pool of present-day Brazilians clearly reflects the imprints of the early Portuguese colonization process (involving directional mating), as well as the recent immigrant waves (from Europe) of the last century.
