Question

In another of his crosses he saw that he got 82 tall plants and 26

short plants. What must have been the genotypes of those parents?

Answer 1

The parents would be heterozygous for the gene, which means (assuming T is representing the dominant gene of tall and t short) the parents genotypes would have been Tt.

Step-by-step explanation:

Dihybrid crosses involving heterozygous parents produce offspring with a phenotypic ratio of approximately 3:1.
