A plant species has two possible gene variations for seed shape: smooth and wrinkled. A plant with smooth seeds pollinates a plant that has wrinkled seeds. There is no chance that their offspring will be born with wrinkled seeds. What can you conclude from this information? The plant with smooth seeds is heterogeneous for the dominant trait.

Both plants are heterogeneous for smooth seeds.

The plant with the smooth seeds is homologous for the dominant trait.

One parent is homologous, and the other is heterogeneous for the dominant trait.

Both genes are co dominant in the offspring.
