Question

Quizplus · Accepted Answer

Monozygotic twins come from a single fertilized egg and therefore share all of their genetic material. Dizygotic twins, on the other hand, come from two separate fertilized eggs and share around 50% of their genetic material, similar to any siblings. Therefore, if a trait has a high heritability, it is more likely to be present in both monozygotic twins than in dizygotic twins.
