What is the missing parent genotype?

If a red flower (EE) is crossed with a yellow flower (ee), how many different phenotypes are possible?

A cross between two purple pea plants yields approximately 25% of the offspring exhibiting white flowers. If purple-flowered plants are dominant to white, what are the genotypes of the parents?
