One flower is heterozygous red and it is crossed with a homozygous white plant. Use a punnet square to determine the probability of their offspring having a white color.

Calculate genotype probabilities: P(WW) = 1/4 = 0.25 or 25% P(WR) = 1/4 = 0.25 or 25% P(Wr) = 2/4 = 0.5 or 50%

Show Dominant pairs (4): WR, RW ,WR, Wr

Calculate genotype probabilities: P(ww) = 1/4 = 0.25 or 25% P(wR) = 1/4 = 0.25 or 25% P(wr) = 2/4 = 0.5 or 50%

Dominant pairs (2): wR Rw

Recessive pairs (2): wr wr

Explanation:

It matters if the white plant is recessive or dominant.
