5a. Which hair color and which hair length is dominant? 5b. What are the genotypes of the parents in mating 1 and mating 2? (For hair color, use Band b for the dominant and recessive alleles respectively; for hair length, use H and h for the dominant and recessive alleles respectively) 5c. If each set of parents produced 64 offspring over their lifetimes, how many of each phenotype would be expected? Use branch diagrams to determine your answer.
