Final answer:
The cross between a homozygous individual (BB) and a heterozygous individual (Bb) can result in offspring with either BB or Bb genotypes.
Step-by-step explanation:
The possible genotypes resulting from a cross between a homozygous individual with genotype BB and a heterozygous individual with genotype Bb would be either BB or Bb. When we list the possible gametes these parents can produce, the homozygous individual can only produce B gametes, while the heterozygous individual can produce B and b gametes. The Punnett square would show that the possible offspring genotypes are either BB (from a B sperm and a B egg) or Bb (from either a B sperm and a b egg, or a b sperm and a B egg). The dominant B allele masks the presence of the recessive b allele, therefore only the dominant phenotype will be expressed.
