In sweet pea plants, the allele for purple flowers is dominant over the allele for white flowers. If half of the plants in one generation of sweet pea plants has purple flowers, what were the most likely genotypes of the parents?

Explanation:

The genotype for parent is going to be purple flower.

After the crossing is done, we have our p1 to be a purple flower dominant over the the yellow that is to say the parent genotype is going to be a Purple denote a capital P

its going to be mutualism cuz they both benefit from the relationship.
