Abstract
One group of 14 albino females of the ST/bJ strain were allowed to mate first with albino males of their own strain and then to black-agouti males of the CBS/J strain. In a second group of 14 albino females, a reverse sequence of matings were arranged. All females were sacrificed and dissected 18 days later. When the albino males had mated first, there were found 113 (95%) albino and 6 (5%) pigmented fetuses. When the black-agouti males had mated first, there were found 88 (70%) albino and 38 (40%) pigmented fetuses. In each experiment the excess of albino fetuses over pigmented fetuses was statistically significant. Various aspects of selective fertilization and its relation to sexual selection are discussed.This publication has 6 references indexed in Scilit:
