phenotype observed in females
phenotype observed in males
N normal phenotype
homeostasis/metabolism
• mice show an increase in Factor V levels
• mice exhibit lower clotting rates and longer clotting times
• mice exhibit short-duration bleeds during ear tagging
• however, no spontaneous bleeds are seen
• activated partial thromboplastin time (aPTT) is increased indicating longer clotting time
• prothrombin time (PT) is increased indicating that blood plasma takes longer to clot

mortality/aging
N
• no spontaneous deaths are seen
