Mark is a gardener who grows snapdragons in her backyard. In snapdragons, flower color is determined by a gene that shows incomplete dominance. A plant with two red alleles (RR) has red flowers, while a plant with two white alleles (WW) has white flowers. If a snapdragon inherits one red allele and one white allele (RW), the result is pink flowers. One day, Mark decides to cross a pink-flowered snapdragon with a white-flowered snapdragon to grow a variety of flowers for an upcoming spring festival. He wants to know what kinds of flowers to expect and how many of each color he might get. a) What flower colors and genotypes can Mark expect from this cross? b) What percentage of the resulting offspring are expected to have pink flowers? c) If Mark grows 40 snapdragons from this cross, how many of them would he likely expect to have white flowers?
