title: Genetic studies of the Syrian hamster. X. Rex.
abstract: The rex mutant has its most obvious effect on coat structure but it also reduces 21-day body weight by about 14 per cent. There is no apparent effect on viability nor on the fecundity of the more robust rex females. Extensive tests for linkage with the genes b, Ba, cd, Ds, e l, Lg, ru, Sa and Wh have proved to be negative. A less extensive test with s was also negative.
