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.
12 lip 2024 · Animals that can produce monozygotic (MZ) twins or quadruplets. (A) The zebrafish janus mutant exhibits the separation of two groups of blastomeres prior to the eight-cell stage, resulting in the development of two distinct spheres (yellow) that ultimately lead to the formation of conjoined fish. If there is limited space between the two groups ...
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...
7 sty 2021 · We first estimated the number of discordant postzygotic mutations in pairs of monozygotic twins (381 twin pairs; 2 triplets) by comparing sequence variation in somatic tissues (1 adipose, 204...
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.
28 wrz 2021 · Monozygotic (MZ) twin births arise when the progeny of a single fertilized egg cell, the zygote, divides into two or more embryos early in development.
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).
