title: Similar pigmentation characteristics in the specific-locus and the mammalian spot test. A way to distinguish between induced mutation and recombination.
abstract: Animals with the same genetic constitution have similar pigmentation characteristics in both the specific-locus and the mammalian spot test. By microscopical analysis it is possible to distinguish between the following genotypes: a/a, p/p--light gray spots; a/a, d/d--gray spots; a/a, cch/c--light brown spots; a/a, b/b--brown spots; a/a, p cch/p cch--near-white spots; a/a, P C/P C--black spots. Near-white and black spots are presumed products of reciprocal recombination, especially if appearing simultaneously as a twin spot.
