Abstract:
A large and ethnically well defined Mandenka sample from Senegal is analysed for 80 nuclear DNA RFLPs, and compared with eight previously studied human populations. A high level of genetic diversity is found in this sample, comparable to that observed in two African Pygmy samples, but lower than that of a European sample. High population variation is observed for most markers. A neutrality test reveals that the markers used in this study can be considered as neutral. A high correlation is found between genetic and geographic distances (r = 0.62), suggesting that geography does also affect long range population genetic relationships and is an important factor behind differentiation among human populations.
