Mouse lines carrying:
Dmrta1tm1.1Zark mutation (0 available); any Dmrta1 mutation (28 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
reproductive system
• most mutant ovaries contain at least one polyovular follicle
• most are biovular, but as many as five oocytes have been observed

behavior/neurological
N
• mice don't display any apparent motor deficits
• females do not show increased aggressiveness toward male intruders compared to wild-type
• male mutants display significantly greater same-sex mounting behavior compared to wild-type (4/16 vs 0 wild-type); proportion of animals with this behavior is low, but consistent upon repeated testing
• occurrence of mounts that are clearly sexual is greater than in wild-type or heterozygotes
• 25% of mutant males consistently display copulatory behavior toward other males

endocrine/exocrine glands
• most mutant ovaries contain at least one polyovular follicle
• most are biovular, but as many as five oocytes have been observed

skeleton
N
• there are no apparent defects in bone or cartilage development

taste/olfaction
N
• males show relatively normal olfactory detection of food or pheromones
