1 To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information.  To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.
Multiple eggs are released or there is more than one ovulation. Both (or more) eggs are fertilized and this is how fraternal twins are made. This can happen with or without fertility drugs. One egg is released but splits in two. This is how identical twins are made. This can happen with or without fertility drugs.
