title: Pelage mutant allele frequencies in domestic cat populations of Poland.
abstract: To determine mutant allele frequencies, surveys of coat phenotypes of the domestic cat (Felis catus L.) were conducted from October 1982 to June 1985 in 23 urban and rural populations of Poland (N = 67-278). The seven gene loci studied included: sex-linked orange (O), agouti (A), tabby (T), full-color expression (D), long hair (L), piebald spotting (S), and dominant white (W). The mutant allele frequencies at these loci are: p(O) = 0-0.139, q(a) = 0.487-0.774, p(Ta) = 0, q(tb) = 0.132-0.451, q(d) = 0-0.332, q(l) = 0-0.220, p(S) = 0.242-0.620, and p(W) = 0. The coefficients of darkness estimated ranged from 0.51 to 0.75, showing no statistically significant differences between urban and rural populations. Of the gene loci studied, only A and S show such differences, with the incidence of alleles a and S being, respectively, significantly higher and lower for urban areas. The relatively great amount of genetic heterogeneity in the cat populations of Poland seems to reflect historical determinants. The Polish data are compared to those from Europe, northern Africa, and western Asia, and geographic patterns in distribution for all of the mutant alleles studied are described.
