HE frequency of occurrence of spontaneous mutations has been under investigation in the extensive mouse breeding colonies of the Jackson Laboratory since the autumn of 1963. The primary goal of this study is to estimate the spontaneous mutation rates, both forward and reverse, at each of five specific coat-color loci (non-agouti, a, brown, b, albino, c, dilute, d, and leaden, In). A secondary g...
The xenotropic and polytropic mouse leukemia viruses (X-MLVs and P-MLVs, respectively) have different host ranges but use the same functionally polymorphic receptor, XPR1, for entry. Endogenous retroviruses (ERVs) of these 2 gammaretrovirus subtypes are largely segregated in different house mouse subspecies, but both MLV types are found in the classical strains of laboratory mice, which are gen...
When the Y chromosome of the laboratory inbred mouse strain C57BL/6 (B6) is replaced by the Y of certain strains of Mus musculus domesticus, testis determination fails and all XY fetuses develop either as hermaphrodites or XY females (XY sex reversal). This suggests the presence of at least two alleles of Sry, the male-determining gene on the Y:M. m. domesticus and B6. The B6 Y chromosome is de...

TUDIES on the inheritance of nonspecific esterase forms of the house mouse (Mus musculus) have recently been reported from the serum (POPP and POPP 1962; PETRAS 1963), kidney ( RUDDLE and RODERICK 1965), and erythrocytes (PELZER 1965). A brief report (SHAW 1964) indicated inheritable esterase differences in kidney homogenates of the deer mouse, Peromyscus maniculatus, and two rare genetically d...
