mortality/aging
• deaths occur within 24 hours
• 15% of pups from mating of the second homozygous generation survive
• 10% of pups from mating of the third homozygous generation survive
• cross fostering pups to wild type parents fails to improve survival
• taurine supplement given to parents before mating and through weaning restores survival rates
|
reproductive system
N |
• expected Mendelian ratios from heterozygous matings
• pregnancy rates from matings of the first three homozygous generations are normal
• rate of live births is normal
|
behavior/neurological
N |
• second generation homozygous females are good nurses when wild type pups are cross fostered to them
