Genetic diversity of Yunnan local chicken breeds and its relationship with origin of Chinese domestic chicken
云南地方鸡种的遗传多样性及其与中国家鸡起源的关系

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.
