Which type of genetic design focuses on comparing behaviors in different environments?

• A. Withdrawal design
• B. Multiple baseline design
• C. Adoption study
• D. Twin study

Answer: (C)

The correct choice focuses on adoption studies, which specifically examine how behaviors and traits are influenced by varying environments by comparing individuals who have been raised in different settings. In adoption studies, researchers can analyze the similarities and differences between adopted children and their biological and adoptive families, allowing them to assess the impact of genetics versus environmental factors on behavior. Adoption studies are particularly valuable because they provide insight into the effects of the rearing environment when genetic factors are controlled. For instance, if adopted children show similar traits to their biological parents, it may suggest a genetic influence, whereas if they resemble their adoptive parents more, this may indicate a stronger environmental impact. This design is instrumental in understanding the nature versus nurture debate, illuminating the complexities behind how various environmental factors can shape behavior.
