What is the difference between mono and dizygotic 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.

How is dizygotic twins produced?

To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.

How are dizygotic twins different to regular siblings?

Dizygotic twins develop in the uterus separately. Because of their being two separate zygotes, the genetic makeup of dyzygotic twins is different, and thus they are not identical. On average, these twins will share half of their genes, just like any other pair of siblings.
