Question

gene (c) controls fur pigmentation in himalayan rabbits. although the two rabbits in the picture have the same genotype, the rabbit reared at temperatures above 30°c has no black fur pigmentation on its ears, nose, and feet.
reared at 20°c or below reared at temperatures above 30°c
the gene c is choose at these higher temperatures. the gene fails to express the particular choose specified by the gene. in this case, choose is an choose influence that affects choose .

Explanation:

1. At temperatures above 30°C, the C gene cannot function to produce pigment, so it is inactive.
2. Genes encode specific traits (phenotypes), here the black fur pigmentation is the trait the gene would express.
3. Temperature is the external factor shown to change the gene's expression.
4. This external factor impacts how the genotype is expressed as a phenotype, so it affects gene expression/phenotype.

Answer:

The gene C is inactive at these higher temperatures. The gene fails to express the particular trait (black fur pigmentation) specified by the gene. In this case, temperature is an environmental influence that affects gene expression (phenotype).
