Allelic frequencies of 15 autosomal STRs from two main population groups (Makua and Changana) in Mozambique

Abstract

and FGA) were determined in 160 samples of unrelated individuals from two main Mozambican´s populations groups namely, Macua and Changana. Statistic parameters of forensic interest were assessed as well as a comparative study with African, European and Latin-American populations. Our data showed no significant differences between Macua and Changana populations (P > 0.05). No deviation from Hardy-Weinberg equilibrium was observed in all 15 autosomal STR loci (P > 0.05). Combined power of discrimination and combined probability of exclusion were 0.99999999997 and 0.999999466 respectively. Locus by locus comparison showed significant differences (P < 0.05) between our population and those from Africa, Europe and South America. Tri-allelic patterns at TPOX locus were found in six samples from two males and four females. We also found allele variant 16.1 at FGA locus in one sample.

Disputed paternity presumption in Burkina Faso: determination of the biological fathers of children using ABO-rhesus/hemoglobin electrophoresis and STR assays

“…In this study, the allele frequencies of the African American population provided in the kit’s user manual were used to calculate the paternity index because there are no great genetic variations between this population and West Africans [ 32 ]. Some studies were done in African countries to determine alleles frequencies [ 33 , 34 ]. Moreover, the STR analysis can be used in forensic investigations.…”
