Illustration showing the development of monozygotic and dizygotic twins. Identical (monozygotic) twins occur when two cells formed by the first division of a fertilised egg develop independently. Non-identical (dizygotic) twins develop when two separate eggs are released from the ovaries and are fertilised simultaneously.
