A defective ecotropic provirus closely linked to the albino locus
Abstract:
A congenic mouse strain (NFS.C) carrying the albino region of chromosome 7 from strain C58/Lw on an ecotropic virus-negative NFS background inherited a noninducible but apparently full-size provirus reactive with an ecotropic virus-specific probe. This unexpressed ecotropic provirus maps close to the albino locus but is distinct from the Fgv-1 provirus located in the same region. The presence of this unique provirus in the albino region of chromosome 7 is potentially important, since it may provide a means of obtaining molecular clones of a chromosomal region, deletions of which are involved in profound metabolic, reproductive, and embryological abnormalities.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
