چکیده
Maternal lineages of West Eurasian and North African origin account for 11.5% total mitochondrial ancestry in Puerto Rico. Historical sources suggest that this arrived mostly from European migrations took place during the four centuries Spanish colonization This study analyzed 101 control region sequences diagnostic coding variants a sample set randomly systematically selected using census-based sampling frame to be representative Rican population, with goal defining Eurasian–North maternal clades estimating their possible geographical origin. Median-joining haplotype networks were constructed hypervariable regions 1 2 various reference populations search shared haplotypes. A posterior probability analysis was performed estimate percentage origins across wide geographic entire most common haplogroups on island. Principal component analyses conducted mtDNA within variation present among all populations. Our shows up 38% Rico likely migrated Canary Islands. However, those haplotypes had previously Islands elsewhere, there are substantial contributions circum-Mediterranean related modern Wolof Serer peoples Senegal nomad Fulani who extend Cameroon. In conclusion, Ricans is geographically diverse. diversity seems low, frequencies have been shaped by population bottlenecks, migration waves, random genetic drift. Consequently, approximately 47% mtDNAs probably early its colonial history

A Mainly Circum-Mediterranean Origin for West Eurasian and North African mtDNAs in Puerto Rico with Strong Contributions from the Canary Islands and West Africa.
Maternal lineages of West Eurasian and North African origin account for 11.5% of total mitochondrial ancestry in Puerto Rico. Historical sources suggest that this ancestry arrived mostly from European migrations that took place during the four centuries of the Spanish colonization of Puerto Rico. This study analyzed 101 mitochondrial control region sequences and diagnostic coding region variant...
متن کاملReconstructing the population history of Puerto Rico by means of mtDNA phylogeographic analysis.
The haplogroup identities of 800 mtDNAs randomly and systematically selected to be representative of the population of Puerto Rico were determined by restriction fragment length polymorphism (RFLP), revealing maternal ancestries in this highly mixed population of 61.3% Amerindian, 27.2% sub-Saharan African, and 11.5% West Eurasian. West Eurasian frequencies were low in all 28 municipalities sam...
متن کاملCOVID-19 Outbreak in Africa: Lessons and Insights from the West African Ebola Virus Disease Epidemics
Over the years, the African continent has had to battle several outbreaks of infectious diseases in different countries. Some of the most deadly were the Ebola virus disease (EVD) outbreaks that occurred in West Africa between 2014 and 2016 affecting Guinea, Liberia, and Sierra Leone and, more recently, from 2018 to 2020 in the Democratic Republic of Congo (DRC). In the era of the COVID-19 pand...
متن کاملThe emerging tree of West Eurasian mtDNAs: a synthesis of control-region sequences and RFLPs.
Variation in the human mitochondrial genome (mtDNA) is now routinely described and used to infer the histories of peoples, by means of one of two procedures, namely, the assaying of RFLPs throughout the genome and the sequencing of parts of the control region (CR). Using 95 samples from the Near East and northwest Caucasus, we present an analysis based on both systems, demonstrate their concord...
