Question

Quizplus · Accepted Answer

Identical twins share 100% of their genetic material and therefore tend to have more similar personalities compared to fraternal twins reared together, who only share around 50% of their genetic material. Studies have shown that identical twins reared apart still share many similarities in personality, despite growing up in different environments, meaning that their genetic makeup plays a larger role in determining their personalities than their upbringing. Therefore, identical twins reared apart tend to have personalities that are more similar than fraternal twins reared together.
