Snowshoe hares change coat color during the year. In the summer, when there is no snow on the ground, their coat is brown. In the winter when there is snow, their coat is white. Which describes the genetic basis for seasonal changes in coat color?

• The snow causes mutations in the genes

• The genes are regulated by hormone signals that are altered by changes in the environment

• Sunlight causes cancer cells to develop

• The genes are deleted during the summer

Which of these studies provides evidence for how environmental factors affect animal growth?

• A study showing that two groups of mice with different genetic backgrounds have the same body weight when raised in the same environment.

• A study showing that juvenile fish grow faster when fed a high-protein diet compared to a low-protein diet, regardless of water temperature.

• A study showing that a particular breed of cattle grows to the same size regardless of whether they are raised in a cold or warm climate.

• A study showing that the body weight of adult dogs is solely determined by their genetics, and environmental factors have no impact.
