辽宁绒山羊7个微卫星位点的遗传多样性分析

Genetic Diversity of Seven Microsatellite Markers in Liaoning Cashmere Goat

试验分析了7个微卫星基因座位OarAE101、OarJMP8、BM143、BM6506、BM1824、BM6438I、LSTS004在辽宁绒山羊4个家系中的遗传多态性。结果表明,7个微卫星标记中仅有4个微卫星位点(OarAE101、OarJMP8、BM143、BM6506)表现出了多态性。OarAE101位点多态信息含量最高,为0.727;BM143位点多态信息含量最低,为0.526。在所标记群体中平均有效等位基因数为3.249个;平均多态信息含量为0.635;遗传杂合度均值为0.638。说明辽宁绒山羊品种内的遗传变异处于一个较高的水平,遗传多样性丰富,选择潜力很大。

The genetic polymorphisms of 7 microsatellite loci（OarAE101,OarJMP8,BM143,BM6506,BM1824,BM6438,ILSTS004） in four families of Liaoning cashmere goat.The results showed that there were 4 microsatellite loci（OarAE101,OarJMP8,BM143,BM6506） showed polymorphism in 7 microsatellit loci.Polymorphic information contents of OarAE101 was the highest,PIC was 0.727,and that of BM143 was the lowest,PIC was 0.526 at 7 microsatellite loci in Liaoning cashmere goat.The average effective numberofallele,the average PIC values and the average genetic heterozygosity were 3.249,0.635 and 0.638,respectively.It showed that variety the hereditary change was in a high level of Liaoning cashmere goat,the heredity multiplicity was very rich,the choice potential was very big.
