Question

Cross a pure-bred tall pea plant with a heterozygous tall pea plant. The allele for tall pea plants is dominant to the allele for short pea plants. What gene combinations can the offspring have? What will the offspring’s phenotypes be? Complete the punnet square.

Answer 1

Genotype combinations: 50% homozygous dominant (TT) and 50% heterozygous (Tt)

Phenotypes: 100% tall pea plants
