Question

Quizplus · Accepted Answer

Studying identical and nonidentical twins allows researchers to compare genetic similarities and differences in relation to helping behaviors. Identical twins share all of their genes, while nonidentical twins share only about 50% of their genes. By comparing the rates of helping behavior in these two groups, researchers can gain insight into the relative contributions of heredity and environment.
