That’s because so-called identical twins pick up genetic mutations in the womb, as their cells weave new strands of DNA and then split into more and more cells. On average, pairs of twins have genomes that differ by an average of 5.2 mutations that occur early in development, according to a new study.

What is the difference between identical twins?

Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.

What are semi-identical twins?

Semi-identical twins occur when one egg is fertilised by two sperm, at exactly the same time, before it divides. Because it’s uncommon for both embryos to survive, semi identical twins are very rare. They can share 50-100% of their genes. If you have found out that a set of twins is about to come into your life, congratulations!
