Abstract

The genetic make-up of five populations of Oreochromis spp. was examined by microsatellite analysis. Eleven polymorphic microsatellite loci showed significant departures from the Hardy-Weinberg equilibrium. The mean heterozygosity ranged from 0.6280 to 0.7040 for each population. The genetic distance values showed a clear separation between O. niloticus and O. mossambicus. The differentiation of the O. niloticus populations was then tested with various genetic measures, which are based on both the Infinite Allele and the Stepwise Mutation models. All these measures grouped the populations similarly.

摘要

通过微卫星分析检测了五个奥利亚罗非鱼种群的基因组成。11个多态微卫星位点显示出显著偏离哈迪-温伯格平衡。每个种群的平均杂合度在0.6280至0.7040之间。遗传距离值表明尼罗罗非鱼和莫桑比克罗非鱼之间有明显的区分。然后用基于无限等位基因模型和逐步突变模型的各种遗传方法对尼罗罗非鱼种群的分化进行了测试。所有这些方法对种群的分组方式相似。
