Luck. There is no way of having identical twins, let alone

choosing the sex.

There are two primary types of twins, Identical and


Identical twins occur when the egg splits after fertilization.

To date no indication of a genetic link has been found. Anyone has

a chance, though small, of having identical twins.

Fraternal twins occur when more than one egg is dropped during

ovulation. This trait can be inherited from the mother's side of

the family. Studies have shown that the chances are also increased

by being overweight or older. Fertility drugs also make this more

likely to happen.
