| 摘 要： | 微卫星DNA又称简单序列重复、短串联重复序列和简单序列长度多态性,广泛存在于真核生物基因组中.微卫星多态性是由于减数分裂过程中不等交换造成变异而产生的,具有保守性,其核心序列为2～6 bp,重复约10～20次,属于等显性遗传.自1989年在人类基因组研究发现微卫星多态性后,目前在马、牛、猪、绵羊和鸡等动物基因组中也筛选出了大量的微卫星标记,但山羊等动物中则相对较少. |
| 关 键 词： | 山羊 微卫星 DNA多态性 |

| Abstract: | Gene frequency, polymorphism information contents, number of effective alleles and heterozygosity were analysed in Xiangdong black goat, Nanjiang yellow goat, Guizhou black goat, Bore goat by using microsatellite markers BMS2508. The results revealed polymorphism content information and number of effective alleles and heterozygosity for BMS2508 in those 4 goat breeds were 0. 804 7,5. 316 3,0. 810 1; 0.689 4,4.404 9,0. 700 6; 0.6910,3.466 3,0.711 4;0.768 8,4. 444 9,0. 775 0 respectively. It couldbe concluded, they were in genetic polymorphism at the microsatellite locus BMS2508. So microsatellite marker BMS2508 could be applied to genetic diversity evaluation in goat breeds . It was also a basis research on relationship between polymorphisms of the microsatellite locus and reproduction performance. |
