There are three alleles controlling the ABO blood types. IA and IB are codominant genes so that the
  combination IAIB produces the AB blood type. The third allele, IO, is recessive to the other two alleles.
  Indicate which of these parents could produce the given child:Parents

Question 2

In a certain breed of chicken, an incomplete dominant gene controls color. The homozygous black,
  when crossed with the homozygous splashed-white, produces an intermediate gray color pattern
  referred to as blue. A second gene controls the shape of the comb. The dominant allele (R) produces
  rose, whereas the recessive allele (r) produces single. Give the F1 and F2 genotypic and phenotypic
  ratios of a cross between a pure-breeding black single and a pure-breeding splashed-white rose. What will be an ideal response?
