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).
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.
21 cze 2015 · By investigating the chromosomes labeling scheme and possible cell labeling combinations, we discover that monozygotic quadruplets may be two pairs of monozygotic twins where the pairs of twins are slightly different from one another.
13 sty 2021 · Looking at 381 monozygotic twin pairs and 2 triplets, the authors first estimated the number of postzygotic mutations present in one twin but not the other.
1 sty 2020 · If two genetically distinct populations of cells were formed before repulsion, another distinct cellular differentiation event would have to occur in at least one of the resultant cell populations at the same embryological state in order to produce monozygotic triplets.
Available hypotheses proposed to explain the mechanism of zygotic splitting fail to explain why monozygotic twins are more prevalent after all methods of assisted reproduction and which struc-ture is likely to control this phenomenon.
