A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51

plants with white flowers. What are the genotypes of the parent plants? Explain

O 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

Rr and ir

O

B.

The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the geneotype of each parent is Rr.

The number of offspring was not large enough to produce the expected results

O

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

    plants with white flowers. What are the genotypes of the parent plants? Explain

    Rr x rr = Rr, Rr, rr and rr

    Parents genotype is Rr and rr

    Explanation:

    Since the parents mated and yielded 47 plants and 51 plants, it reflects that one parent is red flower dominant while the other homozygous white recessive
