A plant heterozygous for stature and fruit flesh color is pollinated by a plant that is homozygous recessive for stature and fruit flesh color. What is the phenotype of the heterozygous plant?

How could the same information still be found with a homozygous dominant donor? Using a homozygous recessive donor is more efficient because the genotype of the unknown parent can be determined in a single generation. If a homozygous dominant donor was used, the unknown genotype could still be determined.
