Verified Answer
Which of the following most appropriately describes haemophilia ? ...
(b) Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern. The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, it is very rare for females to have hemophilia. A characteristic of X-linked inheritance is that fathers cannot pass Xlinked traits to their sons.

Which of the following most appropriately describes haemophilia ? ...
Haemophilia is a genetic disorder that affects the blood clotting ability of an individual. It is caused by the deficiency of clotting factors VIII or IX.
X-linked Recessive Gene Disorder
Haemophilia is an X-linked recessive gene disorder. This means that the genetic mutation responsible for haemophilia is located on the X chromosome, which is one of the two sex chromosomes. Males have one X and one Y chromosome, while females have two X chromosomes. As a result, males are more likely to inherit the disorder, while females are carriers of the mutated gene.
Inherited Disorder
Haemophilia is an inherited disorder, which means that it is passed down from parents to their children through their genes. In most cases, the disorder is passed down from a carrier mother to her son. However, in rare cases, it can also be inherited from a carrier father to his daughter.
Symptoms
Haemophilia is characterized by symptoms such as excessive bleeding, easy bruising, and prolonged bleeding after injury or surgery. In severe cases, spontaneous bleeding can also occur.
Treatment
Haemophilia is a lifelong condition, but it can be managed with proper treatment. Treatment options include replacement therapy, which involves replacing the missing clotting factor with a synthetic version, and gene therapy, which involves introducing a functional version of the clotting factor gene into the body.
Conclusion
To summarize, haemophilia is an X-linked recessive gene disorder that is inherited from parents to their children through their genes. It is characterized by symptoms such as excessive bleeding and easy bruising and can be managed with proper treatment.
