♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
behavior/neurological
submission towards male mice ( J:74988 )
• absence of pheromone-induced aggression towards intruding males
abnormal mating preference ( J:74988 )
• males show indiscriminate mating behavior, mounting both male and female animals

nervous system
abnormal vomeronasal organ morphology ( J:74988 )
• at 2 months of age, mutants have 50% fewer V1R-V3R neurons and 75% fewer V2R neurons
abnormal accessory olfactory bulb morphology ( J:74988 )
• loss of sensory afferents to the accessory olfactory bulb at 1 month of age
abnormal sensory neuron innervation pattern ( J:74988 )
• progressive loss of axon projections in the vomeronasal organ
abnormal nervous system electrophysiology ( J:74988 )
• vomeronasal sensory neurons do not not respond to urine phermones; waveform recorded in vomeronasal organ shows spontaneous firing but not stimulus-driven change in rate

respiratory system
abnormal vomeronasal organ morphology ( J:74988 )
• at 2 months of age, mutants have 50% fewer V1R-V3R neurons and 75% fewer V2R neurons

craniofacial
abnormal vomeronasal organ morphology ( J:74988 )
• at 2 months of age, mutants have 50% fewer V1R-V3R neurons and 75% fewer V2R neurons

growth/size/body
abnormal vomeronasal organ morphology ( J:74988 )
• at 2 months of age, mutants have 50% fewer V1R-V3R neurons and 75% fewer V2R neurons
