1. A particular strain of lily has two variations for flower color: pink and white. Outline a monohybrid cross experiment that could be used to establish which variation is the dominant trait.

2. In snapdragons, the the genes A, B, C, and D assort independently of one another. If an Aa Ba Cc Dd plant is crossed with an Aa bb cc Dd plant, what is the probability of obtaining a snapdragon plant that is phenotypically dominant for all four traits? Explain your reasoning.
