Identical twins arise from a single fertilized egg that for some reason split itself in two. Identical twins have exactly the same genetic make-up.Fraternal twins arise from two separate eggs. Sometimes both of a woman's ovaries will produce an egg cell at the same time. Each of these is fertilized by a separate sperm cell (of which there are always plenty) so they have different genetic make-up. They may share the same womb and be born at the same time but are no more closely related than true brothers.
