title: [The spotted sterile male--a new mutation of dominant spotting on the mouse chromosome 5].
abstract: Spotted sterile male - a new mutation in mice is described (tentative symbol Ssm). White spotting on the belly, legs and tail as well as sterility in heterozygous males Ssm/+ of the B10.M strain are caused by autosomal semidominant gene Ssm. The gene is localized on the 5 chromosome: the frequency of recombination between Ssm and go is 13.6 +/- 1.6%; Ssm is closely linked to Wv. The diheterozygotes Ssm+/+Wv are darkeyed white sterile mice. The deficiency of spermatogenic epithelium cells, emptyness of seminiferous tubules as well as interstitial tissue overgrowing occurred in the testis in sterile males Ssm/+ of B10.M. The fertile hybrid males Ssm/+ are obtained in outcrossing of females Ssm/+ of B10.M with males of YT/Y, CBA/CaY, DBA/2JY, A.CA/Y strains.
