Question

Is haemophilia a pleiotropy?

Answer 1

Haemophilia:

1. Pleiotropy is the phenomenon in which one locus impacts two or more phenotypic traits that appear to be unrelated to one another.
2. No, haemophilia is not a pleiotropic gene.
3. Haemophilia is an inherited bleeding disorder marked by low or absent amounts of clotting factors, which prevent or impair blood coagulation.
4. A classic example of pleiotropy is sickle cell anaemia.
5. This is caused by the gene HbS.
