Allele frequencies of 15 autosomal STR loci in the southern Morocco population with phylogenetic structure among worldwide populations.

Polymerase chain reaction (PCR) amplification using the AmpFl STR Identifiler kit was performed in a random sample of 204 unrelated individuals from the Arabic-speaking population of the southern Morocco. Allele frequencies of 15 STRs loci (D13S317, D16S539, D2S1338, vWA, TPOX, D18S51, D5S818, FGA, D8S1179, D21S11, D7S820, D19S433, CSF1PO, TH01 and D3S1358) have been reported in this population. Markers D18S51, FGA, D2S1338 and D21S11 had the highest power of discrimination (PD) values while TH01 was the most informative locus in the studied population. The phylogenetic tree established among worldwide populations and genetic distance values show a great affinity between the Southern Moroccan population, Saudian, Moroccan of Asni and Andalusian. Our data is useful for anthropological and other comparative studies of populations and is powerful for forensic and paternity testing in the Arabic-speaking population of the Southern Morocco.
