ELECTROPHORETIC VARIATION FOR X CHROMOSOME-LINKED HYPOXANTHINE PHOSPHORIBOSYL TRANSFERASE (HPRT) IN WILD-DERIVED MICE

[摘要] 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.
