hm1

• Allelic Composition: Comt^B2i/Comt^B2i
• Genetic Background: Boulder heterogeneous stock

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

behavior/neurological

behavior/neurological phenotype ( J:162759 )

N • on seven behavioral tests other than novel object exploration, male mice homozygous for this mutation show no significant differences from heterozygous mutant or wild-type male mice

abnormal response to novel object ( J:162759 )

• homozygous mutant male mice visit a novel object less frequently than do homozygous wild-type but more frequently than heterozygous males

• homozygous mutant male mice spend less time exploring a novel object than do homozygous wild-type but more frequently than heterozygous males
