How can you determine the genotype of a plant showing the dominant phenotype of red color? A)The phenotype reflects the genotype,so the plant must be homozygous for the trait. B)Cross the red plant with a white plant to see if any white plants appear. C)Cross the red plant with other red plants to see if any white plants appear. D)Cross the red plant with a white plant to see if any red plants appear.
