What is the genotypic ratio for these two hybrids one hybrid and one homozygote and two homozygotes?

To determine the genotypic ratio for the crosses involving one hybrid (heterozygous, Aa) and one homozygote (AA or aa), you can set up a Punnett square. For a cross between Aa and AA, the genotypic ratio would be 1 AA : 1 Aa. For a cross between two homozygotes (AA x aa), the ratio of genotypes would be 100% Aa. Thus, the ratiOS depend on the specific homozygote involved in the cross.
