Question

The genotype for being a red flower is RR, and the genotype for being a white flower is WW. If the colour of the flower is an example of incomplete dominance, use Punnet squares to show the ratio of the phenotypes in the F1 and F2 generations if you cross a red and a white flower.

Answer 1

Step-by-step explanation:

The F
`_1` and F
`_2` Generations are drawn in Punnett squares below. Please excuse the messy drawings.

Ratios:

F1 Generation:

RW - Red and White Cross - 4/4 = 100%

F2 Generation:

RR - Red only - 1/4 = 25%

RW - Red and White Cross - 2/4 = 50%

WW - White only - 1/4 = 25%
