Abstract

An electrophoretic variation for hypoxanthine phosphoribosyltransferase, HPRT, has been identified in samples of Mus spretus, a field mouse from southern Europe and in M. m. castaneus, a house mouse from southeast Asia. These mice will interbreed with laboratory mice to produce viable, fertile F1 progeny. The variation for HPRT segregates as an X chromosome gene in F1 and backcross progeny. Linkage analysis involving the markers Pgk-1 and Ags indicated a gene order of centromere--Hprt--Pgk-1--Ags in crosses involving both stocks of wild mice.

摘要

在来自南欧的野生小家鼠(Mus spretus)和来自东南亚的家鼠(M. m. castaneus)样本中,已鉴定出次黄嘌呤磷酸核糖转移酶(HPRT)的一种电泳变异。这些小鼠能与实验室小鼠杂交产生可存活、可育的F1代后代。HPRT变异在F1代和回交后代中作为X染色体基因进行分离。在涉及两种野生小鼠品系的杂交中,利用磷酸甘油酸激酶-1(Pgk-1)和精氨酸酶(Ags)标记进行的连锁分析表明基因顺序为着丝粒-Hprt-Pgk-1-Ags。
