In a certain species of pine trees, short needles (S) are dominant to long needles (s). If you cross a long-needled plant with a heterozygous short-needled plant, what will be the genotype ratios of your offspring?

Heterozygous red (Rr) and Heterozygous red (Rr)
One flower is heterozygous red (Rr) and it is crossed with a homozygous white (rr) plant. Use a Punnet square to determine the probability of one of their offspring having a white color.
