dc.description.abstractThis 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 was conducted to compare with 46 Eurasian populations. A probabilistic analysis (Bayesian method) was used with the HVR-I sequences in order to estimate percentages for each continental origin. The results confirm the presence of non-European sub-haplogroups in the western Eurasian mtDNA portion of Puerto Ricans. It was also demonstrated that in a general context the western Eurasian component of Puerto Ricans is more similar to the northern populations of the Fertile Crescent and the Canarian population. The general estimation obtained in the probabilistic analysis of the sequences suggests a major continental component that comes from the Canary Islands. These results confirm that the western Eurasian mtDNA of Puerto Rico is composed by lineages of different geographical origins.
dc.description.abstractEste estudio analizó 102 secuencias de la región control del ADNmt con el propósito de clasificarlas en sub-haplogrupos y estimar su procedencia geográfica continental. En el estudio se realizaron varios análisis de componentes principales del ADNmt euroasiático occidental de Puerto Rico. También se realizó un análisis probabilístico utilizando las secuencias HVR-I para estimar porcentajes de probabilidad de origen geográfico continental. Los resultados demuestran la presencia de sub- haplogrupos no europeos en el ADNmt euroasiático occidental de Puerto Rico. También se demuestra que en términos generales el componente euroasiático occidental de la población de Puerto Rico se asemeja más a las poblaciones del norte de la Media Luna Fértil y a la población canaria. El estimado general obtenido en el análisis probabilístico sugiere una mayor probabilidad de origen en las Islas Canarias. Estos resultados revelan que el ADNmt euroasiático occidental de Puerto Rico está compuesto por linajes de distintas procedencias geográficas.
