Final answer:
Von Willebrand's disease is a genetic disorder characterized by a deficiency or dysfunction of von Willebrand factor (VWF). It is associated with prolonged bleeding time and normal platelet function.
Step-by-step explanation:
Von Willebrand's disease is a genetic disorder that affects the blood's ability to clot. It is characterized by a deficiency or dysfunction of von Willebrand factor (VWF), a protein that plays a key role in the clotting process. The characteristics of von Willebrand's disease include prolonged bleeding time and normal platelet function. Excessive clotting is not a characteristic of von Willebrand's disease, and it is not directly related to deficiencies in factor VIII or excessive production of platelets.
