Genetic analysis of 12 X-chromosome STRs in Western Mediterranean populations.

Abstract

Haplotype and allele frequencies of 12 X-STRs included in the Investigator Argus X-12 kit are reported for 255 individuals, representing four Western Mediterranean populations: Valencia (eastern mainland Spain) and the Balearic Islands (Majorca, Minorca, and Ibiza). Ibiza shows the lowest intra-population variability and the highest level of linkage disequilibrium together with an important genetic distance with regard to the geographically close populations, which is consistent with the historical evidence for long-term demographic isolation and its different matrilineal background.
