mortality/aging
• no homozygous pups are born in matings of heterozygous parents
• no homozygous embryos are found after E10.5
|
cardiovascular system
• may be pericardial swelling
|
cellular
• blastocysts have reduced sensitivity to cell death induced by methylmethanesulfonate
|
• blastocysts have reduced sensitivity to cell death induced by gamma-irradiation
|
embryo
• usually fail to undergo turning
• if turning does occur then neural folds also close and heart looping is seen
|
• posterior truncation
|
• developing limb buds are disorganized at the cellular level with high numbers of pycnotic nuclei
|
• decreased brain vesicle size
|
nervous system
• decreased brain vesicle size
|
limbs/digits/tail
• developing limb buds are disorganized at the cellular level with high numbers of pycnotic nuclei
|
growth/size/body
homeostasis/metabolism
• may be pericardial swelling
