Q. In $Drosophila,$ gene for white eye mutation is also responsible for depigmentation of body parts. Thus , a gene that controls several phenotypes is called

A) Oncogene
B) Epistatic gene
C) Hypostatic gene
D) Pleiotropic gene
Explanation

Pleiotropic gene (Gr. ݈ܲ݁݅݋݊ = ݉ݎ݋݁ (is the gene having the ability to show multiple effects. In݌݋ݏ݋ݎܦℎ݈݅ܽ, a gene for white eye mutation is also responsible for depigmentation of body parts thus a gene controlling more than one phenotype is called as pleiotropic gene.
