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. Environmental control of fur pigmentation in rabbits The gene C is at these higher temperatures. The gene fails to express the particular specified by the gene. In this case, is an influence that affects

its temperature is increasing. this causes molecular vibrations to increase.

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.
