Twins account for more than 90% of multiple births. There are two types of twins – identical (monozygotic) and brother (fraternal). To form identical twins, one fertilized egg (egg) divides and develops two babies with the exact same genetic information.

Does monozygosity mean the same?

Identical twins are also called identical twins. They are fertilized from an egg that splits in two. Identical twins share all of their genes and are always of the same sex. By contrast, fraternal or dizygotic twins are the result of the fertilization of two different eggs during the same pregnancy.

Are Fraternal Twins Identical or Fraternal?

twins can Monozygous (‘same’)which means they develop from a zygote that divides and form two embryos, or are dizygotic (« different » or « fraternal »), which means that each twin is derived from It develops from a single egg, each fertilized by its own sperm cell.

What are the characteristics of identical twins?
