Answer:
The answer is identical twins. Studies examining certain traits are helping to clarify our understanding of the effects of nature and nurture. for example, because<u> identical twins</u> have the same genes, researchers often use them in studies that examine the relative influence of environment and heredity on these traits.

In the biological world, nature is a characteristic that is present in an organism due to the genetic inheritance of the organism from his/her parents. Nurture are the characteristics that are brought in an organism due to the impacts of the environment.
To study the differences between nature and nurture, twins are used for researches. As identical twins have the same genes so researches made on them can clearly determine the influence of the genetic traits as well as the environmental factors on an organism.
