Development

The a^e mutation was discovered by W.F. Hollander and J.W. Gowen among descendants of an irradiated male albino mouse of the S strain then maintained at Iowa State College and a female of the multiple-recessive P testing stock. A single black, typical non-agouti male produced by these matings was bred to three A^Y/A⁺ females (of unidentified background), yielding five male offspring that survived to maturity, three of which proved fertile. Each of these was bred to a female homozygous for the black-and-tan (a ^t) allele, which is recessive to both A^Y and A⁺. Black-and-tan offspring of this cross were bred among themselves, as were progeny of the latter crosses. In one of the resultant lines, the black mice had an extreme non-agouti phenotype, having no yellow hairs. This line contributed to the background of the inbred strain AEJ, which carries a^e. Gdf5^bp-H occurred spontaneously in the PCT multiple recessive stock at Harwell, U.K. It was backcrossed onto AEJ/GnLe-a^e for 5 generations, and the stock has since been maintained by brother-sister inbreeding.
