ABSTRACT: Allele frequency distribution of 10 autosomal STR loci, D3S1358, vWA, D16S539, D2S1338, D8S1179, D21S11, D18S51, D19S433, TH01, and FGA was studied in three ethnic populations such as, Garo, Marma and Rakhains living in different parts of Bangladesh. There were no significant deviations from Hardy–Weinberg equilibrium in any of the loci after Bonferroni correction (p < 0.005) in the studied populations. Forensic efficiency parameters like observed and expected heterozygosity (Ho and He), power of discrimination (PD), power of exclusion (PE), probability of match (PM) and typical paternity index (TPI) were studied for these loci. The combined power of discrimination and combined power of exclusion were >0.9999999999 and >0.9995 respectively in all the populations. A neighbor-joining tree constructed based on pair-wise Nei’s genetic distance by comparing allele frequencies for the 10 STR loci with two other ethnic populations and mainstream Bangladeshi population is also presented.

KEYWORDS: Short tandem repeats, Allele frequency, Heterozygosity, Power of discrimination, Neighbor-joining tree
