. While hiking your find a wild growing pea plant with purple flowers. You know that purple pea flowers are dominant to white pea flowers, but from looking at the plant, you cannot be certain if it is homozygous dominant or heterozygous. Explain the cross you could set up to determine the genotype of the wild pea plant and which results would indicate it is heterozygous versus homozygous.
