Question
Which of the following is true regarding coat color in rabbit?
Himalayan is dominant over chinchilla
Chinchilla is dominant over Himalayan
Himalayan is recessive to albino
Albino is dominant over chinchilla
Himalayan is dominant over chinchilla
Chinchilla is dominant over Himalayan
Himalayan is recessive to albino
Albino is dominant over chinchilla
Hint:
The alleles for Albino, Himalayan and Chinchilla are c, ch and cch respectively.
The correct answer is: Chinchilla is dominant over Himalayan
- Coat color of rabbit is an example of multiple alleles.
- There are 4 different alleles for coat color of rabbit : C, c, ch and cch
- C is the Agouti or black fur coat which is the dominant of all.
- The other three are recessive with chinchilla dominant over albino and Himalayan and Himalayan dominant over albino.
- The correct option is Chinchilla is dominant over Himalayan.

In case of co-dominance:
- A, B and O are alleles responsible for blood groups.
- Neither of the allele is completely dominant over other.
