Think about the phenotypes of the parents and the offspring. You started with two plants which had the same phenotype and when you crossed them, got 3 phenotypes in the offspring. Most of the offspring were the same as the parents but some were red and some were white. Even without the exact numbers of each phenotype, the results should tell you that this is a case of incomplete dominance. You should also be able to predict the whether the parents were homozygous or heterozygous. Which were they?

This means that the red and white flowered plants have what kind of genotype?

With these things in mind you should be able to decide what colors can be crossed to produce the most red flowered plants.

In this case you want to produce the pink phenotype which has a heterozygous genotype. What kinds of genotypes would you cross in order to produce all heterozygous offspring?

If you'd like to try a few different crosses to see what results you might get, use the punnett square below.
