摘　　要：在电泳检测中性结构基因座的基础上采用共显性-共显性模型探讨同羊群体遗传共适应特性。结果表明,在Hb-β-Cat、Tf-ME和CA-ME基因座组合中均存在遗传共适应现象,而且遗传共适应起关键作用,维持着座位间的遗传平衡或者使座位间处于遗传不平衡状态。Genetic co-adaptability of Tong sheep was discussed with co-dominance-co-dominance model based on testing neutral structural loci by electrophoresis. The results revealed that phenomenon of genetic co-adaptability exists among Hb-β-Cat, TfME and CA-ME loci combination. The impact of genetic co-adaptability plays a key part as maintaining genetic equilibrium or arising genetic disequilibrium between loci.
