Family studies usually involve twin and adoption studies to examine genetic and environmental influences on traits and behaviors. Identical twins share 100% of their genes, while fraternal twins share approximately 50% of their genes, allowing researchers to compare the impact of genetics and environment. Adoption studies allow researchers to compare the similarities between biological relatives and adopted relatives, allowing for a better understanding of genetic and environmental influences.
