STR genetic diversity in a Mediterranean population from the south of the Iberian Peninsula

Abstract

Sixteen Y-chromosomal short tandem repeats (STRs) (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4.1) were typed in DNA samples from 52 unrelated men and 15 autosomal STRs (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPOX, vWA) were also studied for a group of 90 individuals (men and women) from the same population (Andalusians from La Alpujarra, South of Spain). The Alpujarrenian population represents an example of an isolated population with remarkable geographical, cultural and historical characteristics. High haplotype diversities were observed for the studied polymorphisms, 0.98 and 1 for YSTRs and autosomal STRs, respectively. Population comparisons for the autosomal STR allele distributions revealed remarkable levels of global homogeneity among samples geographically related.
