Cytological detection of the c-25H deletion involving the albino (c) locus on chromosome 7 in the mouse.

A deletion of the albino (c) locus on mouse chromosome 7 has been demonstrated using Q- and G-banding methods in a mouse heterozygous for the radiation-induced lethal albino allele, c(25H). The deletion, which is thought to be 1-6 cM long, represents about 7.6% of the length of the metaphase chromosome.
