We have examined a polymorphism for the soluble glutamate oxaloacetate (GOT-1) isozyme system which was found in the Asian mouse Mus castaneus. Variants of GOT-1 segregate as though they are controlled by codominant alleles for a single autosomal locus which we have designated Got-1. No close linkage of genes for soluble and mitochondrial forms of the enzyme, GOT-1 and GOT-2 respectively, was observed. Furthermore, no close linkage of Got-1 and the loci c, Gpi-1, Mod-2, Mod-1, Ld-1, Gpd-1, Pgm-1 or Gpo-1 was observed. Our results demonstrate the utility of sampling Mus from diverse populations to extend the repertoire of polymorphic loci and the genetic linkage map.
我们研究了亚洲鼠 Mus castaneus 中谷氨酸草酰乙酸(GOT-1)同工酶系统的多态性。GOT-1 的变体似乎是由单个常染色体座位上的共显性等位基因控制的,我们将其命名为 Got-1。未观察到酶的可溶性和线粒体形式 GOT-1 和 GOT-2 的基因之间的紧密连锁。此外,也没有观察到 Got-1 与 c、Gpi-1、Mod-2、Mod-1、Ld-1、Gpd-1、Pgm-1 或 Gpo-1 基因座的紧密连锁。我们的结果表明,从不同种群中采样 Mus 可以扩展多态性基因座和遗传连锁图谱的范围。
