Step 1
polygenic inheritance.
Answer
The variation in vitamin E amounts observed in the corn plants suggests that multiple genes are influencing this trait. This is characteristic of polygenic inheritance, where a trait is controlled by two or more genes, resulting in a continuous range of phenotypes. The histogram shows a distribution of vitamin E levels among the seeds, indicating that this trait is influenced by multiple genetic factors rather than a single gene.
