Here's a breakdown:

* Polygenic: Meaning "many genes."

* Inheritance: The passing of traits from parents to offspring.

Examples of polygenic traits:

* Height: Many genes contribute to a person's final height.

* Skin color: A range of genes influence the amount of melanin produced, resulting in varying skin tones.

* Eye color: While the basic brown/blue distinction is often linked to a single gene, the full spectrum of eye colors is influenced by multiple genes.

Key features of polygenic inheritance:

* Continuous variation: The trait shows a range of phenotypes rather than distinct categories (e.g., a wide spectrum of heights).

* Bell-shaped distribution: When plotted, polygenic traits often follow a bell curve, with the majority of individuals exhibiting the average phenotype.

* Environmental influence: Polygenic traits are often influenced by environmental factors in addition to genetics.
