Influence of the lethal yellow (Ay) gene on estrous synchrony in mice.
Introduction of an adult male induces partially synchronous estrus in female laboratory mice that have been caged in groups. In the inbred YS/ChWf strain, this effect was observed only when the male was nonyellow (aa), while males heterozygous for the lethal yellow allele (A(y)a) failed to induce synchrony.
