Hi,

Answer:

C) all agouti

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

                                          C+ > Cch > Ch > C.

  • The allele for full colour or agouti is  designated as C+.
  • Allele for mutant coat color  silvery- gray coat-chinchilla is Cch.
  • Allele for “Himalayan” coat is called ‘Ch
  • Albino rabbits have whole white coat and allele for this is c

If we cross homozygous agouti  with homozygous chinchilla the cross will look like this:

P1:                                            agouti x chinchilla

P1:                                         C+C+        X   Cch Cch

F1:                                          C+Cch       :       C+Cch

Since C+ is dominant over Cch, it means that all the offspring will have agouti coat that makes option C correct.


Hope it help
