mortality/aging
• expected number of homozygotes through E10.25
• only 50% of expected number of homozygotes found at E10.75
• no live double homozygotes after E11.5

cardiovascular system
• observed in embryos rescued by tetraploid complementation
• abnormal patterning of the aortic arch, possibly resulting from a defect in neural crest migration
• observed in embryos rescued by tetraploid complementation
• observed in embryos rescued by tetraploid complementation

embryo
• normal morphogenesis and no pathological lesions despite growth retardation at E10.75
• partial rescue of embryonic lethality by tetraploid complementation proves that a problem exists in the placenta
• layer of trophoblast giant cells reduced or absent
• greatly reduced DNA content relative to expectation

growth/size/body
• normal morphogenesis and no pathological lesions despite growth retardation at E10.75

hematopoietic system
• observed in embryos rescued by tetraploid complementation
• reduced DNA content in megakaryocytes relative to expectation observed in embryos rescued by tetraploid complementation

immune system
• reduced DNA content in megakaryocytes relative to expectation observed in embryos rescued by tetraploid complementation
