In a certain type of plant, red flower color is dominant to white flower color. A purebred plant with red flowers was crossed with a purebred plant with white flowers. All the seeds from this cross were collected. One seed was randomly picked from the cross, planted, and allowed to grow under normal conditions. Assume that no mutations occurred.



Which statement explains the probability that the plant will produce red or white flowers?

Answer options with 4 options
A.
There is a 75% chance the flowers will be red and a 25% chance of white, because the red trait is dominant to the white trait.

B.
The chance of red or white flowers is impossible to predict, because the seed was chosen randomly from all the seeds produced.

C.
There is a 50% chance that the flowers will be red and a 50% chance of white, because each parent provides a gene for flower color.

D.
There is a 100% chance that the flowers will be red and a 0% chance of white, because each of the seeds received the dominant

Answered by GPT 3.5
The correct answer is C. There is a 50% chance that the flowers will be red and a 50% chance of white, because each parent provides a gene for flower color. In this case, the red flower color is dominant, but since the plant was crossed with a purebred plant with white flowers, it means that the plant also carries a gene for white flower color. Therefore, there is an equal chance for the plant to produce red or white flowers.
