Samantha and her identical twin were separated at birth. Scientists have said that confounding variables mean that they cannot be sure which of the girls' traits are similar because of their genes and which are similar due to environment. Why?
What will be an ideal response?
Answer: Twin studies cannot rule out confounding variables such as the fact that identical twins look alike. People may treat the twins a certain way based on their identical appearance, which is an environmental influence and not a genetic one.
