Both twin studies and adoption studies are commonly used in behavior genetics research. Twin studies involve comparing the similarities and differences in traits and behaviors between identical and fraternal twins, who share either 100% or 50% of their genes, respectively. Adoption studies involve comparing the similarities and differences in traits and behaviors between adopted children and their biological and adoptive parents, allowing researchers to study the contributions of genetic and environmental factors to individual differences.
