This is when a trait is controlled by more than one gene.

• Multiple alleles

• Polygenetic inheritance

• Codominance

• Incomplete Dominance 

_______ occurs when more than one gene affects a trait

• Incomplete dominance

• Codominance

• Multiple alleles

• Polygenic inheritance

The amount of time it takes for a plant to flower and human height are both examples of which pattern of inheritance?

• Incomplete dominance

• Codominance

• Multiple alleles

• Polygenic inheritance

Which of the following is an example of polygenic inheritance?

• Blood type in humans

• Flower color in snapdragons

• Skin color in humans

• Pea plant height

Polygenic inheritance involves:

• A single gene affecting multiple traits

• Multiple genes affecting a single trait

• A single gene affecting a single trait

• Multiple genes affecting multiple traits

Which of the following traits is most likely to be influenced by polygenic inheritance?

• Eye color

• Sickle cell anemia

• Cystic fibrosis

• Huntington's disease

In polygenic inheritance, the phenotype is often:

• Discontinuous

• Binary

• Continuous

• Unrelated to genotype

Which of the following best describes polygenic inheritance?

• Traits are determined by a single gene with two alleles

• Traits are determined by multiple genes, each with a small effect

• Traits are determined by environmental factors only

• Traits are determined by a single gene with multiple alleles

The height of an individual is an example of polygenic inheritance because:

• It is controlled by a single gene

• It is influenced by multiple genes and environmental factors

• It is not inherited

• It is determined by a single environmental factor
