What are the genotypes of the parents of in this pedigree HH and Hh HH and hh hh and hh Hh and Hh?

To determine the genotypes of the parents in the pedigree, we need to analyze the possible combinations. The combinations of HH and Hh would produce offspring with either HH or Hh genotypes. The combination of HH and hh would produce offspring only with Hh genotypes. The combination of hh and hh would produce only hh offspring, while Hh and Hh would yield a mix of HH, Hh, and hh. Therefore, the possible genotypes of the parents could be HH and Hh, or Hh and Hh, depending on the offspring observed in the pedigree.
