Coloured computed tomography (CT) scan of twin foetuses in a woman's abdomen. Non-identical (dizygotic) twins develop when two separate eggs are released from the ovaries and are fertilised simultaneously. Identical (monozygotic) twins occur when the two cells formed by the first division of a fertilised egg develop independently | |
