Question

select all the correct answers.
sharon has green eyes. her mother has brown eyes, and her dad has blue eyes. which two statements best explain eye color in sharon’s family?
☐ eye color is controlled by many genes.
☐ eye color is inherited from only one parent.
☐ eye color is controlled by only one pair of genes.
☐ eye color is not an inherited trait.
☐ eye color has a polygenic inheritance pattern.

Explanation:

1. Eye color is a polygenic trait, meaning it is controlled by many genes (polygenic inheritance). Sharon's eye color (green) is different from both parents' (brown and blue), which supports that multiple genes are involved, so "Eye color is controlled by many genes" is correct.
2. "Eye color has a polygenic inheritance pattern" is also correct because polygenic inheritance involves multiple genes, and the variation in eye color in Sharon's family (different from both parents) aligns with this pattern.
3. "Eye color is inherited from only one parent" is wrong as traits are inherited from both parents.
4. "Eye color is controlled by only one pair of genes" is wrong because eye color is polygenic (multiple genes), not monogenic (one gene pair).
5. "Eye color is not an inherited trait" is wrong as eye color is an inherited trait passed from parents to offspring.

Answer:

• Eye color is controlled by many genes.
• Eye color has a polygenic inheritance pattern.
