Himalayan rabbits are white over most of the body but have black fur on the ears, nose, feet and tail. The black colour is made by an enzyme that only works below about 33 °C. All rabbits of this breed have the same genotype for coat colour.
Explain how two Himalayan rabbits with the same genotype both show black extremities and a white body.

A Himalayan rabbit was kept in a very warm room for several months. Suggest and explain the effect this would have on new fur growing on its ears.
