摘要: 对上海地区ICR系小鼠的2个远交群和昆明系(KM)小鼠的1个远交群共120只小鼠,用同工酶电泳法和免疫双向扩散法在10个位点上进行了基因型测试,分别计算其表型频率和基因频率,对ICR群体之间、ICR与KM群体之间以及国内外ICR群体之间的遗传特性进行了比较研究。在被测3个群体和对照用1个群体中,ICR群体Ⅰ的遗传性状同对照群相近,ICR群体Ⅱ的遗传性状同KM群体相近。本文还探讨了ICR小鼠和KM小鼠的历史渊源与其遗传特性的联系。

Abstract: "The genetic character of two colonies of ICR outbred mice and one colony of KM outbred mice in Shanghai area was studied by authors using biochemical markers and Ouchterlony methods. The phenotypes of 120 mice in l0 loci were tested, then the phenotype frequency and gene frequency in each colony were calculated. The results of comparative studies showed; (1) in eight loci, there are quite different phenotype frequency and gene frequency between two ICR colonies, especially in Es-3, Gpd-l, He and Idh-1 loci;(2) KM colony has six kinds of phenotype in Es-3 locus and polymorphism is the strain character of KM mice. In six loci (Car-2. Es-3, Gpd-1, Hbb, Idh-l and Mod-1), the gene frequency of KM colony approaches ICR colony Ⅱ; (3) in Es-3, Hbb, Hc, Idh-1, and Mod-1 loci, ICR colony I approaches the control substrain Jct: ICR; but in Gpd-1 locus, JcL:ICR js aproached by ICR colony Ⅱ: in Car-2 locus, Jcl: ICR has its own character. The relationship between the histories of ICR, KM mice and their geneic character was discussed. Authors have indicated the importance of genetic control in reproduction of outbred mice."
