A type of plant that produces red flowers is crossed with a plant that produces white flowers. The alleles for flower color exhibit incomplete dominance, and all of their offspring have pink flowers. If two of the pink-flowered offspring were crossed, which of the following ratios of red, pink, and white flowers would you find in their offspring?
A.0% red : 100% pink : 0% white
B.25% red : 50% pink : 25% white
C.33% red : 33% pink : 33% white
D.50% red : 0% pink : 50% white

This exact question was asked - and answered - last week. So you should be able to find the answer if you scroll down in the forum.
Answer B. - One parent is homozygous for the red flower (AA) and the other homozygous for white flower (aa). No dominance is present in the F1 generation (pink flower). Self fertilization of the gametes in the F1 (AaXAa) gives a 1:2:1 ratio in the F2 generation.
