identical twins are one egg that splits. Non-identical twins are two eggs.

Non identical twins (or fraternal) are made from 2 eggs being fertilized around the same time, by 2 separate sperm.
Identical twins are made after the eggs has been fertilized. During the process the egg completely splits in 2. Hence identical twins have the same genetic makeup

Identical twins are when the babies are from the same egg and non identical are from 2 different eggs that have been released at the same cycle!!

identical twins are "monozygotic" - the are from the same egg ("mono" one + zygote "egg". As the single-celled egg reproduces and divides into more cells, it is possible that they do not remain attached, seperate and develop as seperate foetuses. Identical twins do not have exactly the same DNA as mutations occur during development; but the DNA is similar enough to produce the near-identical appearances.
non-identical twins are "diazygotic" - they come from two seperate fertilized eggs ("dia" two), which are released at the same time by the mother during the menstrual cycle (one from each ovary, instead of just one producing an egg in each cycle).

Fraternal twins-when 2 separate eggs are fertilized
Identical twins- when a fertiilzed egg splits into 2 separate eggs.

well identical twins are made from an egg which splits into two...while normal twins are made when the ovary releases two eggs at the same time making them two different beings!

Identical twins happen when one egg, fertilised by one sperm, splits into two separate eggs. Fraternal twins happen when two eggs are released and are fertilised by two different sperms. Identical twins are the only people who have the same DNA.

identical twins are from the same egg which spits after fertilisation non-identical twin or fraternal twins are when 2 eggs are fertilised

identical twins are from the same egg which splits in two......maternal twins (not identical) are actually two seperate eggs fertilised....women releases two eggs at one time and fertilised by 2 different sperm
