Example 1: Drought decreases plant growth. Without water, even genetically strong plants cannot reach full size.

Effect: _________________ had the bigger effect.

Example 2: Fertilizer increases plant growth. Added nutrients help plants grow faster and larger.

Effect: _________________ had the bigger effect.

Example 3: Plant seed varieties grow differently. In identical conditions, different varieties still show different growth rates.

Effect: _________________ had the bigger effect.

Example 4: Fish size varies by pond. The same fish species grows larger in spacious ponds with abundant food.

Effect: _________________ had the bigger effect.

Your Reasoning
Choose one example above. Explain why you think the environment or genetics had the bigger effect.

Example 4: Effect: Environment had the bigger effect.

Your Reasoning
Example chosen: Example 3 — genetics had the bigger effect.

Because the different seed varieties were grown in identical conditions, environmental differences are not a plausible cause of the growth differences; the variation must come from inherited genetic differences (different alleles affecting growth rate, size, resource use).
Controlling the environment isolates genotype as the primary driver, though environment can still influence the magnitude of genetic effects (G×E interactions).
