Answer 2

Hi,

Answer:

C) all agouti

Step-by-step 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
