Abstract
A polymorphism was found in the electrophoretic mobilities of male-specific rat urinary proteins. The proteins (MUP-1) are inherited as a single autosomal trait. The Mup-1 locus possesses two codominant alleles Mup-1a (fast-migrating type) and Mup-1b (slow-migrating type). Mup-1 is closely linked to b (brown coat color), with a recombination frequency of 7.7 ± 4.3 percent. The similarity of the linkage between Mup-1 and b in mice and rats is discussed.
