Question

During winter, the pigment-producing genes of the arctic fox and other arctic animals do not function and the result is a white coat. This is an example of ___________ change due to environmental influence.

A) codominant
B) genetic
C) genotypic
D) phenotypic

Answer 1

Ans.

The phenotype is defined as physical characteristics or physical expression of that trait. These characters are influenced by genes and environmental conditions. As arctic foxes and other arctic animals show white coat, due to non-functional pigment-producing genes during winters, there is a change in their phenotypic characters (physical appearance).

This show a phenotypic change due to environmental influence as it helps them to adapt in cold environment. Thus, the correct answer is option D). 'phenotypic.'

Answer 2

The correct answer is letter D. This natural physical traits of the fox refers to a phenotypic change. It came from the Greek words “phainein,” which means to show, and “typos,” which means type. This are observable physiological traits of animals that relate to the environment
