Question

Given that the dominance hierarchy of rabbit fur color alleles is C > Cch > Ch, from grey to chinchilla to Himalayan, respectively, what would be the percentage of Himalayan colored rabbits from parents with C Ch and Cch Ch?

a. 0%
b. 25%
c. 50%
d. 100%

Answer 1

The correct option is b) 25%

Step-by-step explanation:

A punnet square can be described as a diagram which illustrates the outcomes of a cross. To check the percentage of Himalayan coloured rabbits lets draw a punnet square.

Cch Ch

C CCch CCh

Ch CCchh CChh

The results from the punnet square depict that there is a 25% chance that the offsprings born from parents having C, Ch and Cchh, Ch alleles will have Himalayan colour. Hence, option b is correct.
