Below are sample questions representative of the exercises included on this worksheet and related 10.68 Polygenic and Environmental Influences on Traits skill assessments:

Problem 1Difficulty: Mastery

Which synthesis statement best aligns with this skill?

AEvery trait is either completely genetic or completely environmental.

BPolygenic traits can be explained by one dominant allele and one Punnett square.

CHeritability estimates remove the need for ethical caution in genetics.

DPhenotypes can arise from inherited variants, environmental conditions, and interactions best studied through distributions and data.

Solution & Explanation:The skill focuses on distinguishing genetic, environmental, and gene-environment contributions using population-level evidence and careful interpretation.

Problem 2Difficulty: Mastery

Use the clone reaction-norm graph for dry and wet soil. What does the crossover pattern indicate?

AWet soil changes clone A into clone B.

BOnly one environment was measured.

CThe best-performing clone depends on the soil-water environment.

DThe clones have identical phenotypes in both soils.

Solution & Explanation:Crossing lines show that genotype rankings reverse across environments, a strong sign of gene-environment interaction.

Problem 3Difficulty: Mastery

A direct-to-consumer report gives a customer a high polygenic score for a complex trait. Which guidance is most responsible?

ATell the customer the trait outcome is guaranteed.

BExplain uncertainty, privacy, population limits, and the role of environment before making any interpretation.

CIgnore family history and environmental information.

DPost the score online because genetic data are never sensitive.

Solution & Explanation:Responsible interpretation of polygenic information includes uncertainty, context, consent, privacy, and environmental influences.
