摘　　要：A total of seventeen caprine microsatellite markers were used on 169 goats to investigate genetic diversity of eight Cameroon native goat populations and to assess genetic differentiation with the East African small goat. All microsatellites showed a high polymorphic content （PIC） of more than 0.5 in almost all ecotypes. These microsatellite markers were useful for native goat ecotypes variability assessment. Expected heterozygosity of all ecotypes was above 0.5, varying from 0.2 to 0.7. Only goats from Eastern rainforest ecotype deviated from Hardy-Weinberg equilibrium test （P 〉 0.001）. Although geographic distribution was a good indication of differentiation, there appeared a tendency of genetic exchange between various ecotypes in Cameroon native goats.
