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

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

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

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
