A pleiotropic gene

A

controls a trait only n combination with another gene

B

controls multiple traits in an individual

C

is expressed only in primitive plants

D

is a gene evolved during Pliocene

Text Solution

Verified by Experts

The correct Answer is:
B
The ability of a gene to have multiple phenotypic effects because it influences a number of characters simultaneously is known as pleiotropy. The gene having a multiple phenotypic effect because of its ability to control expression of two or more characters is called pleiotropic gene. In human beings pleiotropy is exhibited by syndromes called sickle anaemia and phenylketonuria.
