Identical twins, who share the same genetic makeup, are often compared to fraternal twins, who share approximately 50% of their genes.

Which of the following statements best describes the primary purpose of conducting twin studies in the context of genetics and behavior?

To demonstrate that all traits are purely hereditary.
