| 摘 要： | 选用位于绵羊第6号染色体上与多羔基因FecB紧密连锁的微卫星座位LSCV043,300U和BMS2508,对32只小尾寒羊的多态性和产羔性状进行了研究,结果发现:3个微卫星座位在小尾寒羊中的等位基因数分别为11、8和10;3个微卫星座位的多态信息含量、遗传杂合度和有效等位基因数分别为0.851/0.878/7.39,0.822/0.853/6.24,0.858/0.885/7.75.LSCV043的基因型139 bp/115 bp对应的小尾寒羊产羔数最小二乘平均值最高,为3.67只/胎;300U的基因型172 bp/156 bp对应的最小二乘平均值最高,为4.00只/胎;BMS2508的基因型178bp/166 bp对应的最小二乘平均值最高,为4.00只/胎.

| Abstract: | Three microsatellite loci(LSCV043,300U,BMS2508)linked to FecB gene mapped to chromosome 6 were selected to analyze the genetic polymorphism and to detect the correlation to litter size traits in Small Tail Han sheep breed(32 individuals as materials).The results showed that the numbers of alleles for this three microsatellite loci were 11,8,10 in Small Tail Han sheep.The PIC,H and Ne of LSCV043,300U and BMS2508 were 0.851/0.878/7.39,0.822/0.853/6.24,0.858/0.885/7.75 respectively.Least squares means of the litter size for the genotype 139/115bp of LSCV043,the genotype 172/156bp of 300U and the genotype 178/166 bp of BMS2508 were the highest(3.67,4.00,4.00number born/litter). |
