How are twins produced?

 Q:   Ask a Question about How are twins produced?       
How are twins produced? Twins may be absolutely identical, or only as similar as a typical brother or sister. Identical twins are produced when the embryo splits into two in the early stages of its development. This produces two identical children of the same sex. Non-identical twins are produced when two eggs are released at the same time and both are fertilized. They can be the same sex, or brother and sister.

One in 83 pregnancies results in twins. Identical twins look so alike they can only be told apart by fingerprints.

The bones of a baby's head are not fully fused at birth, allowing the skull to pass though the mother's birth canal. The bones gradually become joined, but a gap at the top of the skull, called the fontanelle, does not close up for several months.
