∙ 6y agoIdentical twins are formed when one sperm fuses with one egg cell and results in a zygote as the normal procedure is, then this ball of cell divides into two to give two genetically identical masses of cells which then grow independently, all by themselves. Usually between the identical twins one is much healthier than the other
A single egg is fertilised

How do twins form?
Identical twins form when an egg is released from the ovary and is fertilised by a sperm and then splits into two. They then form naturally. Non-identical twins form when two eggs are released from the ovary and then fertilised by a sperm. They also form naturally. Identical twins have to be of the same sex (two boys or two girls) because they have come from the same egg which contains the same DNA. Non-identical twins can be either boy and girl or of the same sex (two boys or two girls) because they came from two different eggs and so have two different sets of DNA.
