phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• homozygous mice spend less time exploring open arms in the elevated plus-maze test
• mice demonstrate increased tendency to stay at the sides of an open field box and spent less time in active locomotion or rearing activity
• increased mean latency in jumping response in the hot-plate test, but no difference in the tail-flick test
• males do not initiate copulatory behavior

endocrine/exocrine glands
• degeneration noted with age

growth/size/body
• the body weight of homozygous animals at 7 weeks of age are approximately 70% of controls

homeostasis/metabolism

reproductive system
• little or no movement; do not fertilize oocytes in vitro
• degeneration noted with age
• absent spermatozoa
• decreased number of late spermatids
• males do not plug females

cellular
• decreased number of late spermatids
• little or no movement; do not fertilize oocytes in vitro
