mortality/aging
• number of homozygous pups is at lower than the expected Mendelian ratio at weaning
|
reproductive system
N |
• normal sperm production and normal testis weight
|
• abnormal gap at the mid-piece/annulus junction
|
• less defined mitochondrial cisternae and the mitochondrial matrix appears more electron dense
|
• significant decrease in progressive motility but no significant difference in total sperm motility
|
• sire smaller litters when crossed to wild-type females(average litter size 4.5 pups compared to 6.9 pups for wild-type males)
