2. In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers.
What are the genotypes of the parent plants?
a. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.
b. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio, so the genotypes of both parents are Rr. The number of offspring was not large enough to produce the expected results.
c. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.
d. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.
