A multiple pregnancy from a single zygote is called monozygotic, from two zygotes is called dizygotic, or from three or more zygotes is called polyzygotic. Similarly, the siblings themselves from a multiple birth may be referred to as monozygotic if they are identical or as dizygotic (in cases of twins) or polyzygotic (for three or more ...
10 lip 2024 · Monozygotic (MZ) twins are believed to arise from the fission of a single fertilized embryo at different stages. Monochorionic MZ twins, who share one chorion, originate from the splitting of the inner cell mass (ICM) within a single blastocyst.
22 lip 2024 · A monozygotic triplet pregnancy carries the risks of a monozygotic pregnancy with a shared placenta, plus the additional risks of a triplet pregnancy. A pregnancy of this type could be more likely...
13 sty 2021 · A new study in Nature Genetics used whole-genome sequencing of monozygotic twins, their parents, partners and offspring to identify and characterize early developmental mutations, as well as the...
Zygosity refers to the genetic makeup of the pregnancy, or the number of zygotes that become fertilized leading to a multiple birth. Twins, in rarer cases triplets, quadruplets (four), quintuplets (five), arising from a single fertilized ovum are termed monozygotic (MZ).
1 sty 2020 · Zygosity is the term that describes the number of zygotes from which a multiple pregnancy is produced. In the simplest form, twins may either be monozygotic (i.e., produced from a single zygote) or polyzygotic, namely, dizygotic, trizygotic, etc. (i.e., produced from two, three or more zygotes).
7 sty 2021 · Whole-genome sequencing of monozygotic twins, along with their parents, spouses and children, identifies postzygotic mutations present in the somatic tissue of one twin, but not the other, and...
