Question

Quizplus · Accepted Answer

Correlational studies of twins have provided strong evidence that certain psychological disorders are strongly linked to genetic factors. This is because identical twins, who share 100% of their genes, have a higher concordance rate for many psychiatric disorders compared to fraternal twins, who share only approximately 50% of their genes. This suggests that genetic factors play a significant role in the development of these disorders.
