reproductive system
• pregnancy is prolonged by 2 days in 2 of 11 mutants and by 1 day in 3 mutants and pseudopregnancy is extended by 2.5 days
• duration of continuous diestrus is prolonged by about 1.5 days
• the number of pups, especially live pups, is decreased

homeostasis/metabolism
• serum progesterone levels do decline before parturition as in wild-type and are low enough for delivery of pups, however levels are still 1.3 times higher than in wild-type
