Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. Assume all
PolarNik [594]

Answer:

C) all chinchilla

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 chinchilla with homozygous chinchilla the cross will look like this:

P1:                                            chinchilla x chinchilla

P1:                                             Cch Cch    X   Cch Cch

F1:                                          Cch Cch       :       Cch Cch

Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype  it means that all the offspring will have chinchilla phenotype that makes option C correct.

Hope it help
