The role of environmental factors on gene expression is illustrated by
A) the varying plant height of genetically identical yarrow plants when grown at different elevations.

D) the fur pattern of Himalayan rabbits.
E) all of these.

Question

Quizplus · Accepted Answer

All of these examples illustrate how environmental factors can affect gene expression. The varying plant height of genetically identical yarrow plants when grown at different elevations shows how environmental factors such as sunlight, temperature, and precipitation can affect gene expression. The flower color of hydrangeas grown in soils of differing pH shows how soil acidity can affect gene expression. The depression response that some persons make to very stressful situations can be influenced by environmental factors such as social support, upbringing, and life experiences. The fur pattern of Himalayan rabbits is determined by both genetics and environmental factors such as temperature.
