Below are sample questions representative of the exercises included on this worksheet and related 7.49 Environmental and Genetic Influences on Traits skill assessments:

Problem 1Difficulty: Mastery

A scientist compares two grape varieties (V1 and V2) across three vineyards. V1 consistently produces more sugar in grapes than V2 at each vineyard. However, both varieties produce the most sugar in the sunniest vineyard and the least sugar in the cloudiest vineyard.

Which claim is best supported?

ASugar content depends only on vineyard sunlight and not on variety.

BSugar content is influenced by both genetics (variety) and environment (sunlight differences among vineyards).

CSugar content depends only on variety and not on sunlight.

DSugar content depends only on how often the vines are trimmed.

Solution & Explanation:Variety differences at the same vineyard show genetics. Changes across vineyards with different sunlight show environmental influence, so both factors affect the trait.

Problem 2Difficulty: Mastery

A large study of height finds: - Children with taller parents tend to be taller.,,Science - Children who had long‑lasting illness during early childhood are often shorter than expected for their family.,,Science - When illness is prevented with vaccines and good healthcare, average height in the community increases over generations.,Science "

Which claim is best supported?,A. Height depends only on the amount of homework. | B. Height depends only on healthcare and not on parents. | C. Height is influenced by both genetics (parent height) and environment (health and disease). | D. Height depends only on parents and not on illness.,C,Parent‑child patterns support genetic influence

Problem 3Difficulty: Mastery

Eczema (itchy skin inflammation) is more common in some families. A student with family history has mild eczema most of the year. When they start using a harsh soap and take very hot showers, their eczema flares up. When they switch to gentle soap, the flare‑ups decrease.

Which claim is best supported?

AEczema depends only on genes and never changes with soap.

BEczema can be influenced by both genetics (family tendency) and environment (skin irritants like harsh soap).

CEczema depends only on soap and not on family history.

DEczema depends only on the season of the year.

Solution & Explanation:Family history suggests genetic predisposition, and changes in soap and shower habits causing flare‑ups show an environmental trigger.
