Final answer:
Alexii's hemophilia first appears when he experiences bleeding from wounds and when blood leaks into joint spaces, urine, and stool. This is caused by the inadequate production of clotting factors, specifically factor VIII or factor IX. Hemophilia is usually passed from a carrier mother to her male offspring.
Step-by-step explanation:
Hemophilia is a group of genetic disorders that affect the body's ability to control blood clotting. In the case of Alexii's hemophilia, it is likely to first appear when he experiences bleeding from even minor internal and external wounds, and when blood leaks into joint spaces after exercise and into urine and stool.
This is due to the inadequate production of clotting factors, specifically factor VIII or factor IX, which are responsible for blood clotting. Hemophilia is typically passed from a healthy carrier mother to her male offspring, since males are XY. Females would need to inherit a defective gene from both parents to manifest the disease.
