Both homozygous and heterozygous mice with the contrasted induced mutation (<i>Kitl<sup>Sl-con</sup></i>) are viable.  Male homozygous mutant mice are fertile but females are usually sterile.  Mice heterozygous for the contrasted mutation are recognizable soon after birth by dark pigmentation of the genital papilla with the adult coat being slightly lighter than normal.  Homozygous mutant mice also have dark genitalia and a markedly diluted coat and mild macrocytic anemia.

These mice carry a radiation-induced mutation characterized by female sterility, dark genitalia with a diluted coat, and mild macrocytic anemia.

Typically mice are recovered in 12-16 weeks. Contact Customer Service to place an order or for more information.
