In four-o'clocks, the allele for red flowers is incompletely dominant over the allele for white flowers, so all heterozygotes have pink flowers. If you cross a white flower with a pink flower, what is the phenotypic ratio of the F1 generation (i.e., the offspring that are produced)?   a. 1 red: 2 pink: 1 white   b. 0 red: 2 pink: 2 white   c. 1 red: 0 pink: 3 white   d. 1 red: 1 pink: 2 white   e. 0 red: 4 pink: 0 white

      a.

    1 red: 2 pink: 1 white

      b.

    0 red: 2 pink: 2 white
