3D ultrasound scan of triplet foetuses at 15 weeks. Non-identical (dizygotic) triplets develop when three separate eggs are released from the ovaries and are fertilised simultaneously. Identical (monozygotic) triplets occur when cells formed by the first division of a fertilised egg develop independently. | |
