phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• approximately 25% died within the first 3 weeks of life
• additional mice died in the 4th week of life, but in contrast to Ebf3tm1Reed homozygotes, the majority of mice survived to adulthood

behavior/neurological
• females showed slightly reduced mating efficiency
• males exhibited a dramatically reduced mating efficiency

nervous system
• olfactory glomeruli absent from dorsal olfactory bulb
• olfactory neurons fail to project to the dorsal olfactory bulb
