WHat is pleiotropy ?

anonymous · Answer

Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect. Consequently, a mutation in a pleiotropic gene may have an effect on some or all traits simultaneously.

So its A?

abhisar · Answer

That's correct, Albinism is associated with a number of vision defects, such as photophobia, in addition to skin color. This means the gene responsible for Albinism is controling more than one trait and hence it is an example of Pleiotropy.
