Explain what twin studies are and why they are used in behavior genetics research.
What will be an ideal response?
Behavior geneticists use twin studies to try to determine the role of heredity for a given behavior or characteristic. Identical twins share the same genetic material, so any differences in their behavior could be attributed to environmental factors. Researchers frequently compare results of research conducted with both identical twins and fraternal twins. Several issues complicate the interpretation of twin studies. For example, perhaps the environments of identical twins are more similar than the environments of fraternal twins.
