Twins can be identical, also known as monozygotic, or non-identical, also known as dizygotic. 'Fraternal twins' is another term for non-identical twins. Identical twins share the same genetic material and are always the same sex.
Identical twins, also known as monozygotic twins, form when a single fertilised egg splits into two and grows into two separate embryos. The twins are the same gender, have the same blood type and share physical traits such as eye colour, hair colour and facial features. Identical twins may or may not share a placenta and/or amniotic sac.
