Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.75 Adaptation and Fitness. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Adaptation and Fitness: Students distinguish adaptations from acclimation, identify environmental context, and predict how traits affect fitness in specific conditions. Rigor range: standard concept checks through honors/Pre-AP/AP-ready evidence, phylogeny, population, and evolutionary mechanism analysis.

Below are sample questions representative of the exercises included on this worksheet and related 10.75 Adaptation and Fitness skill assessments:

Problem 1Difficulty: Mastery

A long-term plant study shows that drought years favor deep-root alleles, while several wet years favor shallow-root alleles. Both alleles remain in the population for decades. Which explanation is best?

ABoth alleles remain only because selection has stopped completely.

BDeep-root and shallow-root alleles must have identical fitness in every year.

CThe plants are adapting as individuals rather than through allele-frequency changes.

DFluctuating selection can maintain variation when different alleles have higher fitness under different conditions.

Solution & Explanation:When environmental conditions alternate, selection can favor different alleles at different times. This can preserve genetic variation instead of fixing one allele.

Problem 2Difficulty: Mastery

Use the contour plot titled 'Fitness Landscape for Two Traits.' Which conclusion is best supported?

ATrait 1 alone determines fitness because Trait 2 is on the vertical axis.

BAll trait combinations have equal fitness because they appear on one plot.

CThe highest fitness occurs where both traits are near the central high-fitness peak.

DFitness is highest at every edge of the plot.

Solution & Explanation:A fitness landscape shows how combinations of traits affect reproductive success. The peak marks the trait combination with the highest fitness.

Problem 3Difficulty: Mastery

Across a mountain slope, darker insects are common in cool forests and lighter insects are common in hot grasslands. Which evidence would best support adaptive clines rather than random patterning?

AThe insects are found at different elevations, with no fitness measurements.

BColor genotypes have higher survival and reproduction in the temperature zones where they are common.

CCollectors prefer one color over the other.

DEvery insect changes color permanently after moving uphill.

Solution & Explanation:A geographic pattern suggests a cline, but adaptive interpretation requires linking heritable color variation to fitness across environments.
