Twin and adoption studies
Twin studies are the majorly significant tool in dissecting the nature versus nurture argument. Identical twins are siblings whose genotypes are replicates of each other. They are more likely the best symbol of whether biology affects traits and psychopathology in human beings. For example, if one twin has dark hair, then the other twin has dark hair as well; this aspect of the similar genes would ideally distribute itself toward the phenotypes of nature and personality of the identical twins. Twin studies has been well established that the argument about the nature and nurture influence on the human nature cannot full without exploring research on twin studies.
