1 those who study the role of genetics in human behavior make the assumption that a. all behaviors are the result of a single gene. b. environmental factors play no role in human behavior. c. behavior has a biological origin d. behavior is learned.

Explanation:

Researchers studying genetics in human behavior focus on biological underpinnings of actions. Option A is incorrect as behaviors rarely stem from a single gene. Option B is wrong because they do not ignore environmental factors. Option D aligns with nurture-focused theories, not genetic approaches. Only option C reflects the core assumption that behavior has a biological (genetic) origin.
