They are formed from two individual eggs which are fertilised by two separate sperm. A boy and girl twins cannot be identical.

Monozygotic or identical twins are usually of the same sex as they are formed from a single zygote (fertilised egg) which contains either male (XY) or female (XX) sex chromosomes.

Fraternal twins develop separately from each other in their mother’s uterus and are surrounded by their own amniotic membranes.

Each baby has its own placenta for obtaining nutrients from the mother.

How do Fraternal Twins Occur?

Since the widespread acceptance of fertility treatments, there’s been a high rate of dizygotic twins.

In rare cases, a mother who is already pregnant releases another egg in the same month which is then fertilised by a separate sperm. This phenomenon is called superfetation.

However, this can only occur few weeks after the conception of the first baby.

This may lead to one fraternal twin becoming bigger and more mature than the other at birth.

It is also possible for a woman to have fraternal twins with two different biological fathers.

This can occur when she ovulates while already pregnant with one baby.

A simultaneous pregnancy happens when the second egg is fertilised by a sperm from a different partner.

There’s a possibility for triplets to comprise of a set of identical or fraternal twins and a singleton.
