If black fur color is controlled by a dominant allele (B) and brown by its recessive allele (b), give the
  genotypes of the parents and offspring of a cross of a black male with a brown female that produces
  1/2 black offspring and 1/2 brown offspring. What will be an ideal response?
 
 

Question 2

In poultry, rose comb is controlled by a dominant allele and its recessive allele controls single comb.
  (a) Give the genotype and phenotype produced from crossing a pure-breeding, rose comb
  chicken with a pure-breeding, single comb chicken.
  (b) Give the results of the backcross of the F1 hybrid with both pure-breeding parents. What will be an ideal response?
