Haemophilia is a genetic disorder primarily associated with a deficiency in specific clotting factors, predominantly factor VIII (in Hemophilia A) or factor IX (in Hemophilia B). One of the hallmark clinical manifestations of this disorder is hemarthrosis, which refers to bleeding into the joints. This condition is often debilitating, leading to pain, swelling, and potentially long-term joint damage if not managed properly. Individuals with hemophilia frequently experience recurrent episodes of hemarthrosis, especially in weight-bearing joints like the knees, elbows, and ankles.

The other options don't accurately characterize haemophilia. Daughters being affected from their carrier fathers is a misunderstanding of the inheritance pattern, as haemophilia is X-linked recessive, and typically it is sons who would be affected, while daughters would usually be carriers. The presence of haemophilia is related to the X chromosome, not the Y chromosome, and therefore option related to the Y chromosome is also incorrect. Lastly, while factor VII deficiency is a bleeding disorder (specifically Hemorrhagic disease of the newborn or associated with other conditions), it is not the specific deficiency seen in haemophilia. Instead, haemophilia is most commonly related to deficiencies in factors VIII or IX
