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.
7 sty 2021 · When DNA isolated from the blood of monozygotic twins is sequenced and compared, some of the differences seen may be due to somatic mutations in blood cells or their precursors. Such mutations...
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...
10 lip 2024 · Cases of MZ twins from IVF clinics were found by using combinations of terms including ‘monozygotic twins’ with ‘IVF case report’, ‘ART’, ‘single embryo transfer’, or ‘dichorionic’. The papers retrieved were categorized based on the implicated mechanisms or as those with unexplained mechanisms.
10 gru 2011 · Monozygotic (MZ) twins originate when a single egg is fertilized to form one zygote, which then divides into two embryos. Although they share the same genotype they are not phenotypically identical.
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.
1 sty 2020 · Monozygotic twinning is one of the commonest major congenital abnormalities with an overall incidence at birth of 1:250. The different aspects of the genetic aetiology of this discordance in monozygotic twins will be discussed in this chapter.
