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) 75% (3/4) 75% (3/4) 100% (4/4) 100% (4/4) 50% (2/4)
The correct answer is 75% (3/4).
When two heterozygous purple plants (Pp) are crossed, the possible genotypes of the offspring are PP, Pp, and pp.
Among these, only the PP and Pp genotypes would result in the purple flower phenotype.
Therefore, 3 out of 4 possible genotypes would have the same phenotype as the parents, resulting in a 75% chance of the offspring having the same phenotype.
