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 50% (2/4) 50% (2/4) 25% (1/4) 25% (1/4) 100% (4/4) 100% (4/4) 75% (3/4)
The correct answer is 100% (4/4). When two heterozygous purple plants (Pp) are crossed, the possible genotypes of the offspring are PP, Pp, and Pp. All of these genotypes will result in a purple flower phenotype since the trait for purple flowers is dominant over white flowers. Therefore, all of the offspring are expected to have the same phenotype as the parents.
