N normal phenotype
growth/size/body
• when the allele is inherited paternally, mice exhibit a 20% decrease in weight compared to wild-type mice beginning at E17.5 and continuing throughout adulthood
• however, when this allele is inherited maternally mice have normal weights

mortality/aging
• when is Igf2rtm2Wag inherited paternally and Thp is maternally, some mice survive birth and reach maturity despite some prenatal lethality
• when the allele is inherited paternally, fewer than expected mice are born
• however, unlike when only Thp is inherited maternally, some mice are recovered at birth

• when is Igf2rtm2Wag inherited paternally and Thp is maternally, mice have a bent tail compared to wild-type mice

reproductive system
N
• when the allele is inherited paternally, mice are fertile
