| 摘 要： | 对国内外29个鸡种5个血液蛋白质多态位点上等位基因频率进行遗传距离的计算,并进行了聚类分析。结果表明,原产于意大利的来航鸡和原产于英国的罗斯鸡亲缘关系最为接近;亚洲鸡种间的亲缘关系较近;而家鸡与原鸡间的亲缘关系较远。就4种原鸡(红色原鸡、灰色原鸡、锡兰原鸡、绿颈原鸡)而言,以红色原鸡和家鸡的亲缘关系较为接近。聚类图一方面反映出鸡种之间因地理隔离造成的遗传分化,另一方面也说明红色原鸡可能是家鸡的主要祖先。

| Abstract: | Cluster analysis was made for the gene frequencies of 5 blood protein polymorphic loci with 29 domestic and foreign chicken breeds. The results showed that the nearest genetic relationships between Leghorn originated in Italy and Ross Brown with English origin. Chicken in Asia were generally close, whereas domestic fowls showed a distant relationship with jungle fowls. Compared with other three jungle fowls (e. g. Gray Jungle Fowl, Ceylonese Jungle Fowl, and Green Jungle Fowl). Red Jungle Fowl had a close relation with domestic fowl. The dendrogram indicated that the genetic divergence of different chicken breeds result from the geographical isolation, it also showed that Red Jungle Fowl was probablly the main ancestor of domestic fowls. |
