| 摘 要： | 为了分析微卫星标记ILSTS011的遗传多态性,研究以河南省地方绵羊品种大尾寒羊、小尾寒羊和豫西脂尾羊为研究对象,采用聚丙烯酰胺凝胶电泳技术分离微卫星标记的带型.结果表明:在3个绵羊品种中均检测到微卫星标记ILSTS011有3个等位基因,微卫星标记ILSTS011的平均杂合度为0.614 1,平均有效等位基因数为2.614 0,平均多态信息含量为0.551 3.说明ILSTS011为高度多态基因座,可作为有效的遗传标记用于大尾寒羊、小尾寒羊和豫西脂尾羊的遗传多样性分析.

| Abstract: | In this study,one microsatellite marker was used to analyze genetic variation and polymorphism of three local sheep breeds in Henan province: fat-tail sheep,small tailed han sheep and Yuxi fat-tailed sheep.The genotypes were determined manually after polyacrylamide gel electrophoresis.The results show that three alleles were observed in each sheep population.Average heterozygosity,average number of valid alleles,average PIC of marker ILSTS011 were 0.614 1,2.614 0 and 0.551 3 respectively,which shows the sel... |
