Question

In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h). 

Show punnet squares

  1. In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like? 
  2. If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype?
  3. If you carried out this test cross (from 2, using the F1 from 1), what phenotypes and in what ratio would you expect?
  4. What phenotypes in what ratio would be expected in the F2 generation of the cross in point 1?
