monozygotic twins

Monozygotic twins, also known as identical twins, develop when a single fertilized egg splits into two separate embryos early in pregnancy. Because they originate from the same fertilized egg, they share nearly identical genetic material, which is why they often look very similar. Despite sharing the same genes, differences can still occur due to environmental factors and individual experiences. Monozygotic twins are a natural example of how genetics play a significant role in our development, but they also emphasize the complex interaction between genes and the environment in shaping who we are.
