Question

A gene that shows its effect on more than one character is

• A. Polygene
• B. Pleiotropic gene
• C. Multifactor gene
• D. Multiple gene.

Answer 1

Answer: (B)

Pleiotropic gene

The ability of a gene to produce more than one phenotype in an organism is called Pleoitrophy and the genes are called Pleiotripic genes. It is not essential that the traits are equally influenced. Sometimes, the effect of the gene is more evident in case of one trait and less evident in case of another trait.

So, the correct option is ‘Pleiotropic gene’.
