mortality/aging
• Background Sensitivity: the majority of mice on a C57BL/6J congenic background die within 1 day of birth when this allele is inherited paternally unlike mice on a mixed 129 and C57BL/6J background
• however, mice that survive more than 2 days survive into adulthood

embryo
• expanded volume and increased labyrinthine trophoblasts when this allele is inherited maternally
• reduced volume and decreased labyrinthine trophoblasts when this allele is inherited paternally
• however, mice exhibit normal junctional zone, decidual basalis and chorion regardless of allele inheritance
• increased when this allele is inherited maternally
• decreased when this allele is inherited paternally
• when this allele is inherited paternally
• when this allele is inherited maternally, mice exhibit enlarged placenta first apparent at E16.5 and at E18.5 compared with wild-type mice
• increased theoretical diffusion capacity and specific diffusion capacity when this allele is inherited maternally
• decreased theoretical diffusion capacity and specific diffusion capacity when this allele is inherited paternally

growth/size/body
• when this allele is inherited paternally
• however, mice exhibit normal fetal weight and after birth growth when this allele is inherited maternally
• into adulthood when this allele is inherited paternally
• at E16.5 when this allele is inherited paternally
