ABSTRACT
Burkina Faso (BF) is a landlocked Sahelian country located in the middle of West Africa. Sixty-three local languages are spoken in BF. Despite this high diversity, the BF population remains poorly investigated, and updated forensic parameters with a large number of Y chromosome short tandem repeats (Y-STRs) are still missing. Herein, 447 DNA samples were typed for a cocktail of 29 Y-STR loci. None of these 447 individuals in total shared a common haplotype. The overall Y-STR haplotypes were successfully uploaded online on the Y-STR Haplotype Reference Database (YHRD) with the accession numbers YA004690 and YA004691. The main haplotype diversity was 0.9999999965, which is much higher than that obtained with 12 Y-STRs in a previous study. Haploid Match Probability for the whole dataset was 0.002237. The phylogenetic analysis of 24 ethnic groups of BF shows that the ethnic group named BISSA is closer to Gur speakers than Mande speakers, where they belong. In addition, genetic structure analysis of 49 African subpopulations sheds light on the fact that geographic proximity turns out to be one of the best predictors of genetic affinity between populations.
