Question
2. In four-o’clocks, the allele for red flowers is incompletely dominant to the allele for white flowers, so
heterozygotes have pink flowers. What ratios of
flower colors would you expect among the offspring
of the following crosses: (a) pink × pink, (b) white ×
pink, (c) red × red, (d) red × pink, (e) white × white,
and (f) red × white? If you specifically wanted to produce pink flowers, which of these crosses would be
most efficient?
