Final answer:
Polygenic traits are controlled by multiple genes and are not governed by Mendel's rules of inheritance. Examples in humans include height, skin color, and weight.
Step-by-step explanation:
Polygenic traits are traits that are controlled by more than one gene. These traits are not governed by Mendel's rules of inheritance. Instead, they involve the combined effects of multiple genes, each of which may have two or more alleles. Polygenic traits can be measured and often exhibit a wide range of variability. Examples of polygenic traits in humans include height, skin color, and weight.
