Which statement supports the relationship between behavior and gene expression?
A) A person can change his or her genome only with medical treatment.
B) By repeating an activity many times, a person can affect how certain genes are expressed in the brain.
C) Behavior affects gene expression in infancy, and then the environment takes over.
D) Elderly people are more susceptible to behavioral shifts because their gene expression is unstable.

Question

Quizplus · Accepted Answer

Research suggests that repetitive behaviors and experiences can alter gene expression in the brain, leading to changes in behavior. This is known as experience-dependent gene expression. While medical treatments can potentially change aspects of a person's genome, this statement does not directly support the relationship between behavior and gene expression. Option C implies that behavior has a limited effect on gene expression, which is not supported by current research. Option D does not accurately reflect how gene expression changes with age.
