Frizzy (fr) is a spontaneous recessive mutation in mice characterized by curly vibrissae, a disheveled coat and short hair (Snell 1951). Previous linkage analysis located the mutant fr allele on Mus musculus Chromosome 7 (Falconer and Snell 1952)....
Rats lacking normal hairy coats were discovered several years ago among our colony of hairy albino rats. The trait was found to be controlled by a recessive allele of a gene we designated shorn (shn), which mapped to distal end of rat chromosome 7....
Ahearn et al. (J. Heredity 93:210-213) have previously shown that the rat fuzzy and Charles River "hairless" mutations are defects in the same gene on rat Chromosome 1, and are likely orthologues of mouse frizzy (abbreviated fr) on mouse Chromosome...
