13. The roseatte spoonbill is a bird that lives in mangrove marshes and captures insects with a long spoon-shaped bill. Bill color is due to a gene that has two incompletely dominant alleles. Individuals that are homozygous for one allele have a black bill. Individuals that are homozygous for the other allele have a bill that is almost white. What color bill will heterozygous individuals most likely express? Explain the reasoning/rationale behind your answer.
