3 Short fur in cats is dominant to long fur Two heterozygous

3. Short fur in cats is dominant to long fur. Two heterozygous short fur cats are crossed. If they have four kittens, what is the probability that they will have the following phenotypes?

a) all short fur cats

b) EITHER all short fur OR all long fur

c) Three short fur and one long fur

Solution

heterozygous indicates the alleles are like this Hh for father and Hh for mother and when crossed will give the following combinations HH Hh Hh and hh and this will lead to three of short fur because of the dominant allele and one long fur cat with both recessive allele combinations.
