How can two plants with different genotypes have the same phenotype?

The simplest way that two plants can have different genotypes, but the same phenotype, is if they both have a dominant allele for the same trait.

For example, the genotypes Pp and PP, will both produce the phenotype created by P (for example, pink colored petals). This is because P is dominant to p, and will always be expressed.

Other ways that the same phenotype can be created from different genotypes are when the environment affects the traits, or when the trait is controlled by more than one gene.

Hope this helped.
