  • Multiple pregnancy involves more than one embryo (fetus) in any one gestation. Two independent mechanisms may lead to multiple gestation: segmentation of a single fertile ovum (identical, monovular, or monozygotic) or fertilization of separate ova by different spermatozoa (fraternal or dizygotic) multiple pregnancy. In the development of twins (the most frequent higher-order gestation), monozygotism is constant ( 2.3–4/1000 deliveries), whereas dizygotism has certain predispositions. Dizygotic twinning is inherited as a recessive autosomal trait via the female descendants.
