31 sie 2022 · We present a case of monozygotic (identical) triplets who have each transitioned from female to male under the care of a university transgender health service. Each triplet experienced gender dysphoria from childhood and has undergone transitional endocrine care and various aspects of gender-affirming surgery.
26 mar 2022 · The principal finding of our study was that in triplet pregnancies, FR to twin or singleton pregnancies reduced the risk of low birthweight and PTB at <34 and <32 weeks of gestation and increased the live birth rate without markedly changing the odds of early pregnancy loss and neonatal death compared with literature on expectant management of ...
The processes that give rise to monozygotic (MZ) twins remain elusive. This article describes various theories of MZ twinning that have been examined over the years, although they continue to be speculative.
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.
7 sty 2021 · We analyzed the set of 705 pre-PGCS mutations identified in the trio and three-generation approach and compared it to a set of 321,106 mutations from 5,515 trios where family members did not...
12 lip 2005 · Fraternal, or dizygotic, twins are different in their genetic make-up whereas identical, or monozygotic, twins are genetically the same. Monozygous twins develop from the same ovum, therefore they share identical genetic information.
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).
