| 摘 要： | 本研究用12种识别六碱基的限制性内切酶对来自云南省3个地方绵羊品种11个样本的线粒体DNA(mtDNA)进行了限制性片段长度多态性分析(RFLP),结果表明,云南绵羊群体平均核苷歧异度为0.086%,平均遗传距离为0.00 4,说明mtDNA变异度很低,遗传多样性贫乏,提示云南绵羊可能起源于同一个共同祖先;昭通绵羊与德钦绵羊距离较远,大约分歧于30万年前,德钦绵羊与腾冲绵羊大约分歧于11万年前,而腾冲绵羊与昭通绵羊也于18万年前发生分歧。
Abstract:mtDNA from 11 sheeps samples of Deqin,Zhaotong and Tengchong in Yunnan province was analyzed with 12 restriction endonucleases.14 restriction types were observed which could sorted into 3 haplotypes.The estimated number of nucleotide substitutions per site(π)in Yunnan sheep was 0.086% and the mean genetic distance(P) was 0.004.This results might show a pattern of single origin of Yunnan sheep.Divergencetime of the native sheep flocks from three districts of Yunnan were estimated on the mean rate of sequence divergence of 0.01 per million years in mtDNA.
