What factor distinguishes the degree of similarity in identical twins versus dizygotic twins over time?

Question

Quizplus · Accepted Answer

The degree of similarity in identical twins becomes more similar over time due to the fact that they share 100% of their DNA and any differences that emerge throughout development become more apparent. On the other hand, the degree of similarity in dizygotic twins does not become more similar over time as they share only 50% of their DNA, the same as any other sibling pair, and any differences may become less apparent over time due to environmental factors.
