Twins foetuses. Computer artwork of different coloured twin foetuses in the womb. Non- identical (dizygotic) twins develop when two separate eggs are released from the ovaries and are fertilised simultaneously. Identical (monozygotic) twins occur when two cells formed by the first division of a fertilised egg develop independently | |
