mortality/aging
N
• Background Sensitivity: normal numbers of homozygotes are produced in heterozygous x heterozygous matings; however, numbers are reduced on the FVB/N background
• Background Sensitivity: the adult mortality rate is similar to control, however, the rate is higher in the mixed C57BL/6;129P2 and FVB/N backgrounds

mortality/aging
• Background Sensitivity: the adult mortality rate is higher in mice on the mixed and FVB/N backgrounds, but not on the C57BL/6 background
• Background Sensitivity: fewer homozygotes are produced in heterozygous x heterozygous matings

homeostasis/metabolism
• serum 17beta-estradiol levels are reduced prior to 6 weeks of age

integument
• delayed mammary gland development is observed in 5-6 week old females
• numbers of proliferating epithelial cells are reduced in the mammary glands from 5 week old females as compared to controls
• mammary glands exhibit reduced numbers of terminal end buds, secondary branching and outgrowth length, however, differences disappear by 3 months of age

endocrine/exocrine glands
• delayed mammary gland development is observed in 5-6 week old females
• numbers of proliferating epithelial cells are reduced in the mammary glands from 5 week old females as compared to controls
• mammary glands exhibit reduced numbers of terminal end buds, secondary branching and outgrowth length, however, differences disappear by 3 months of age

reproductive system
• uterine weight is decreased at 5-6 weeks, but is similar to controls by 7 weeks
• females older than 3 months are infertile
• pregnancy rate is lower in 6-12 week old females
