Q. The pleiotropic character represents that quality of gene in which it can

Solution:

A gene which can regulate and express multiple phenotypic characters is called a pleiotropic gene. The underlying mechanism of pleiotropy in most cases is the effect of a gene on metabolic pathways which contribute towards different phenotypes. An example of this is the disease phenylketonuria, which occurs in humans.
