A mutation to an apparently new allele at the W-locus of the mouse arose spontaneously in
a cross between two inbred strains. Heterozygotes have a broad white sash, leading to the
name and symbol sash, Wsh. Homozygotes are black-eyed whites which are viable, fertile
and not anaemic, although the gene does cause mild haematopoietic defects. The original
mutant animal also carried a spontaneous recessive lethal mutation on chromosome 5,
mapping at 2 cM distal to the W-locus.
