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

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

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.
