In pea plants, the trait for purple flowers (P) is dominant over the trait for white flowers (p). If two heterozygous purple plants are crossed, what percentage of the offspring would be expected to have the same phenotype as the parents?(1 point) Responses 25% (1/4) 25% (1/4) 50% (2/4) 50% (2/4) 75% (3/4) 75% (3/4) 100% (4/4)
The correct answer is 50% (2/4).
When two heterozygous purple plants (Pp) are crossed, they can produce four possible genotypes in their offspring: PP (2), Pp (2), and pp (0).
The phenotypes would be purple for PP and Pp, while pp would have the white phenotype.
Therefore, 2 out of the 4 possible genotypes would have the same purple phenotype as the parents, which is 50%.
