Abstract

Sesquizygotic twinning (SZT) is one of the rarest events that can occur in multiple pregnancies. It has only been reported twice to date. Studies indicate that sesquizygotic twins result from the splitting of a chimeric embryo at an early stage. Theories and studies suggest that SZT represents a third unique twinning mechanism that is different from dizygotic and monozygotic twinning; however, the unique features of SZT have nothing to do with the twinning mechanism. Instead, it resembles more of an atypical monozygotic twinning form according to the twinning mechanism.

同卵双胞胎：一种独特的双胞胎类型，而不是机制。

半同卵双胞胎（SZT）是多胎妊娠中最罕见的事件之一。迄今为止只报道过两次。研究表明，半同卵双胞胎是嵌合胚胎早期分裂的结果。理论和研究表明，SZT代表了不同于异卵和同卵双胞胎的第三种独特的孪生机制；然而，SZT的独特之处与孪生机制无关。相反，根据双胞胎机制，它更像一个非典型的同卵双胞胎形式。

期刊介绍： An international journal dedicated to the rapid publication of original research in early embryology, Zygote covers interdisciplinary studies on gametogenesis through fertilization to gastrulation in animals and humans. The scope has been expanded to include clinical papers, molecular and developmental genetics. The editors will favour work describing fundamental processes in the cellular and molecular mechanisms of animal development, and, in particular, the identification of unifying principles in biology. Nonetheless, new technologies, review articles, debates and letters will become a prominent feature.
