Flower color in snapdragons is due to a gene with incomplete dominance: C^RC^R plants have red flowers, C^RC^W have pink flowers, and C^WC^W plants have white flowers. What types and ratios of flower color are expected among the progeny of a cross of pink × white? A)1 red:2 pink:1 white B)1 red:1 pink C)1 pink:1 white D)all pink E)all white

The cross is between a pink snapdragon (C^RC^W) and a white snapdragon (C^WC^W). When the two snapdragons are crossed, their possible gametes are: Pink snapdragon: C^R and C^W White snapdragon: C^W and C^W A Punnett square can be used to determine the potential phenotypes of the offspring: | | C^R | C^W | |---|---|---| | C^W | Pink | White | | C^W | Pink | White | The resulting genotypes are C^RC^W (pink) and C^WC^W (white). Therefore, the expected phenotype ratio in this cross is 1:1, or 50% pink and 50% white.
