| Ay and other mutations at the a locus conferring a completely yellow coat color are dominant to all a alleles that produce a darker coat. Hair pigment of Ay heterozygotes is yellow, but eyes are black. Heterozygotes usually become obese and infertile within a few months after birth. Increased adipose tissue mass is due to fat cell hypertrophy, and it has been hypothesized that the obesity results from the observed reduction in hypothalamic norepinephrine and dopamine. Heterozygotes are more susceptible to several kinds of tumors than are normal mice, possibly due, at least in part, to a general increase in cell proliferation that also manifests as a slight increase in lean body mass and skeletal length. Further spleen cells from heterozygotes cause a significantly lower graft vs. host reaction. Mice homozygous for the yellow spontaneous mutation (Ay) die before implantation, or shortly thereafter. The time of death and
