a scientist conducted an expirement to determine the effect of the enviroment on the color of fur of a himalayan rabit
Evgen [1.6K]

The Himalayan rabbit's environment entirely determines the color of its coat.  

<h3>How does the environment affect the coat color on the fur of a Himalayan rabbit? </h3>

The color of newborn Himalayan rabbits is either white or light grey. Beginning at the age of four weeks and ending at six months, coloring the coat is a process. The temperature of the environment affects the color of the coat, which grows darker in colder climates and lighter in warmer ones. The Himalayan rabbit's hair turns black when it is subjected to subfreezing conditions. That area's fur finally turned black. The rabbit's newly grown fur will be black in color if the white fur is removed and the animal is kept at a low temperature. Considering this, it is clear that temperature affects the expression of genes that control this organism's fur color.
