Below are sample questions representative of the exercises included on this worksheet and related 7.56 Artificial Selection and Human Influence skill assessments:

Problem 1Difficulty: Mastery

Scientists develop a wheat variety by editing a gene so the plant makes less of a protein that causes allergies. They then cross the edited wheat with high-yield wheat and select offspring that keep the edit and high yield.

Which statement best describes the whole process?

AIt is natural selection because wheat chooses the best yield.

BIt is cloning because crossing always makes identical plants.

CIt is only environmental change because allergies are not genetic.

DIt combines genetic engineering to create a specific change with selective breeding to spread that change into a high-yield background.

Solution & Explanation:Artificial selection means humans decide which organisms get to reproduce based on a trait. Here, editing creates the change; breeding spreads and combines it, so the trait is more likely to be passed to offspring.

Problem 2Difficulty: Mastery

A wildlife reserve breeds endangered frogs in captivity. They choose breeders that survive a disease challenge, but they also rotate breeders to avoid close relatives mating. "

Why would the reserve do both things?,A. To increase disease resistance while also keeping genetic diversity high enough to avoid inbreeding problems. | B. Because diversity makes the frogs forget how to reproduce. | C. Because inbreeding always creates new helpful traits quickly. | D. Because selection and diversity cannot happen together.,A,Artificial selection means humans decide which organisms get to reproduce based on a trait. Here

Solution & Explanation:answer choices

Problem 3Difficulty: Mastery

A researcher claims that cloning is the best way to improve a crop because it always creates better traits each generation.

Which response is most accurate?

ACloning mixes genes from two parents to create new traits.

BCloning copies traits without creating new combinations; improving traits usually requires selecting among variation, which cloning does not increase.

CCloning stops inheritance because there are no seeds.

DCloning always causes mutations that improve traits.

Solution & Explanation:Artificial selection means humans decide which organisms get to reproduce based on a trait. Here, cloning preserves traits but doesn't create new combinations, so the trait is more likely to be passed to offspring.
