Final answer:
Polygenic traits, such as height and skin color, are controlled by multiple genes with multiple alleles. They exhibit a wide range of variability and can be influenced by environmental factors.
Step-by-step explanation:
In polygenic inheritance, a trait is controlled by more than one gene. Examples of polygenic inheritance include height or skin color. The expression of these traits is influenced by multiple genes with multiple alleles. Polygenic traits exhibit a wide range of variability and can be affected by environmental factors. This type of inheritance is different from Mendelian inheritance, where traits are controlled by a single pair of genes. Polygenic traits, such as height and skin color, are controlled by multiple genes with multiple alleles. They exhibit a wide range of variability and can be influenced by environmental factors.
