Genetic ancestry in Afro-descendants from the Andes and Pacific Coast regions of Ecuador

      Abstract

      This study aimed to investigate genetic diversity and ancestry in Afro-descendants from the Andes (AN) and the Pacific Coast (PC) regions of Ecuador, using autosomal and lineage markers. CR-mtDNA and PPY23-STRs showed high haplotype diversities. Statistically significant differences were found between AN and PC. Due to different patterns of sex-biased matting, differences between regions were more pronounced for the mtDNA than for the Y-chromosomal markers. A lower African ancestry was detected in AN than PC, for autosomal and both maternal and paternal lineage markers.
