Behavioral geneticists are interested in understanding the role that genetics play in shaping individual differences in behavior, personality, and mental health. One of the most common research methods employed by behavioral geneticists is to examine heritability using twin and adoption studies. By comparing the similarity of traits and behaviors in genetically identical twins versus fraternal twins, as well as in adopted individuals compared to their biological and adoptive families, researchers can estimate the degree to which genetics may be playing a role in these individual differences.
