There is a no chance that their offspring will be born with wrinkled seeds. What can you conclude from this information? A. The plant with smooth seeds is heterozygous for the dominant trait. B. Both plants are heterozygous for smooth seeds. C. The plant with the smooth seeds is homozygous for the dominant trait. D. One parent is homozygous, and the other is heterozygous for the dominant trait. E. Both genes are codominant in the offspring.
