How are identical twins genetically similar and different?
Quick Answer
Identical twins begin from the same fertilized egg, so they start with almost the same DNA. Over time, small mutations and epigenetic differences can make them less identical.
The Full Story
Monozygotic twins form when one embryo splits into two. At birth, they usually have nearly the same genetic sequence, which is why they often look very similar and share many traits. As they grow, random mutations, epigenetic changes, and environmental influences can create differences in gene activity and health. This is why identical twins can still differ in fingerprints, disease risk, and personality traits.
