There is a recessive coat coloration pattern in rabbits, and some dogs and cats called Himalayan. A Himalayan animal has darker fur on colder parts of the body (ears, nose, feet, tail). This is part of a multiple allele system: brown (C) is dominant to both white (c) and to Himalayan (ch), and Himalayan is dominant to white.
A brown male is mated to a Himalayan female, and they have offspring of all three coat colors, brown, white and Himalayan. What are the parents' genotypes?
