dc.description.abstractThe 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 published RFLP and control region sequence information of 1931 samples with Sub-Saharan African ancestry from Puerto Rico, Dominican Republic, Brazil, and various African populations to explore the extent to which different regions in Africa have contributed to the present day composition of Puerto Rican maternal lineages. The results show that almost 60% of the Sub-Saharan African haplogroups present in the island are exclusive of or more common in the West African populations, and 26.5% in the West-Central African region. These results are in complete agreement with historical literature that strongly limits the participation of eastern African populations during the Atlantic slave trade, while supporting the western and west-central contributions.en_US
dc.description.abstractLa composición genética matriarcal de 79 muestras puertorriqueñas con ascendencia africana del sur del Sahara fue examinada utilizando análisis de restricción (RFLP por sus siglas en inglés). Los datos obtenidos fueron combinados con información publicada de RFLP y secuenciación de 1931 muestras con ascendencia africana de Puerto Rico, República Dominicana, Brasil y varias poblaciones africanas para explorar hasta qué punto las regiones geográficas del continente africano han contribuido a la composición de linajes maternales en la población puertorriqueña actual. Los resultados demuestran que casi el 60% de los haplogrupos africanos sub-saharianos en la isla son exclusivos o más comunes en poblaciones del oeste de África y que el 26.5% lo es en la región occidental de centro África. Estos resultados concuerdan con la literatura histórica que limita la participación de poblaciones del este de África durante la trata de esclavos africanos, mientras establece una contribución significativa del oeste y centro-oeste del continente africano.en_US
