Twin studies
Pairs of twins are valuable subjects for human geneticists and psychologists who want to find out to what extent certain characteristics are genetically determined and what role environmental conditions play. Of particular interest here is how much more similar identical twins are compared to fraternal twins. The degree of genetic similarity differs between identical (100%) and fraternal twins (50%). However, they live in a similar environment, so the degree of greater similarity between identical twins compared to fraternal twins can be used to estimate the genetic contribution to traits such as intelligence. In this case, depending on the study, it was estimated to be between 50 and 80 percent, depending on whether the environmental differences in the population (health care, access to education) are large or small.
