摘要

本研究旨在使用常染色体和谱系标记调查来自安第斯山脉（AN）和厄瓜多尔太平洋海岸（PC）地区的非洲后裔的遗传多样性和祖先。CR-mtDNA和PPY23STRs具有较高的单倍型多样性。在AN和PC之间发现了统计学上的显著差异。由于性别偏见的matting模式不同，mtDNA区域之间的差异比Y染色体标记更明显。在常染色体和母系和父系谱系标记方面，AN的非洲血统低于PC。

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

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.
