The Bubi population of Equatorial Guinea characterised by HUMTH01, HUMVWA31A, HUMCSF1PO, HUMTPOX, D3S1358, D8S1179, D18S51 and D19S253 STR polymorphisms

Allele frequencies for eight STR loci (HUMTH01, HUMVWA31A, HUMCSF1PO, HUMTP OX, D3S1358, D8S1179, D18S51, D19S253) have been analysed in the Bubi popul ation of Bioko Island, Equatorial Guinea. For all loci, no deviation from H ardy-Weinberg equilibrium was found. Data obtained were compared with that of Caucasian and African populations. Significant differences were found fo r all systems between all the black populations compared and the Caucasoid population. Similarities were observed between the Bubi and Zimbabweans, an d also with African American populations. Also, more affinities were observ ed between Zimbabweans and Ugandans and Ovambos than between these groups a nd the Bubi population. From these comparisons it is suggested that in Afri ca, as in other continents, there is a certain genetic heterogeneity.
