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.
O
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 ir
