On his farm, a farmer cultivates hot pepper plants and sweet pepper plants in separate fields. Every year, he keeps seed from the pepper plants so that he can produce the following season’s crop of peppers. In one year, he observes that some of the seeds taken from the sweet pepper plants have developed into plants that bear both hot and sweet peppers. What is the most likely explanation?
- ASelf-pollination has occurred and pollen has been transferred from the anther of a hot pepper plant to the stigma of a sweet pepper plant.
- BCross-pollination has occurred and pollen has been transferred from the stigma of a hot pepper plant to the anther of a sweet pepper plant.
- CSelf-pollination has occurred and pollen has been transferred from the stigma of a hot pepper plant to the anther of a sweet pepper plant.
- DCross-pollination has occurred and pollen has been transferred from the anther of a hot pepper plant to the stigma of a sweet pepper plant.
