摘  要:
利用建立的小鼠微卫星检测方法,对来源于2个单位的近交系 BALB/c 小鼠和封闭群 ICR 小鼠进行了遗传分析,结果发现 A 单位 BALB/c 小鼠发生了遗传污染,有部分小鼠在部分微卫星位点发生了变异,而 B 单位 BALB/c 小鼠在所有的检测位点上的结果都与预期的 BALB/c 小鼠位点一致;对 ICR 小鼠分析结果发现 A 单位 ICR 小鼠在22个位点的平均杂合度为0.379,平均多态信息量为0.308,属中度多态,B 单位 ICR 小鼠的平均杂合度为0.287,平均多态信息量为0.227,属低度多态。结果表明微卫星标记可用于检测近交系小鼠的遗传质量,也可用于分析封闭群小鼠的遗传多态性,为一种有潜力的实验动物遗传学检测标记。

摘  要:
To analyze the genetic quality of BALB/c and ICR mice from two units.The result showed that the BALB/c mice from Unit A was genetic contaminated,some of the mice were mutated in some microsatellite loci,and BALB/c mice from Unit B was coinci- dence with the expecting result of the standard BALB/c strain.The ayerage heterozygosity and polymorphism information content of 22 microsatellite loci of ICR mice from Unit A was 0.379 and 0.308 respectively,this indicated that ICR mice from Unit A was medium genetic diversity,and the average heterozygosity and polymorphism information content of ICR mice from Unit B was 0.287 and 0.227,this showed that ICR mice from Unit B was low genetic diversity.So themicrosatellite marker can not only detect the genetic quality of inbred mice,but can also analyze the genetic polymorphism of closed colony.The microsatellite marker is a potential mark- er for monitoring the genetic quality of laboratory animals.
