摘要
云南地方鸡种在生境、形态外貌、细胞遗传和血液蛋白等方面均表现出多样性，但mtDNA的遗传变异单一。云南地方鸡种有其独特的基因类型，由于所处的特殊地理位置和生态条件差异，形成了与我国其它鸡种相对独立的鸡种。从血液蛋白、细胞遗传和mtDNA等方面进一步证明红色原鸡为家鸡的祖先。云南可能是中国家鸡的起源中心之一。
The habtat, appearance, karyotype, and blood protein locus of Yunnan local chicken breeds are diverse, but no mtDNA polymorphism exists inferrd from restriction endonuclease analysis. Due to different geological locations and ecological condition, Yunnan local chicken breeds have their unique gene types, relativelyindependent of other Chinese chicken breeds. The results from blood protein, karyotype and mtDNA demonstrate further that Gallus domesticus originated from Gallus gallus. Yunnan is probably one of the originalcenter of Chinese domestic chicken.
