WebMonozygotic twinning (MZT) occurs when an embryo splits after fertilization, resulting in identical twins. The incidence of MZT is 0.42% naturally (in normal pregnancies). With the use of assisted reproduction, the incidence of MZT has increased, and currently varies between 1.2% and 8.9%. Webdizygotic twin, also called fraternal twin or nonidentical twin, two siblings who come from separate ova, or eggs, that are released at the same time from an ovary and are fertilized by separate sperm. The term originates from di, meaning “two,” and zygote, “egg.” The rate of dizygotic twinning varies considerably worldwide.
