A genome wide linkage scan for dizygotic twinning in 525 families of mothers of dizygotic twins [PDF]
Human Reproduction, 2010 The tendency to conceive dizygotic (DZ) twins is a complex trait influenced by genetic and environmental factors. To search for new candidate loci for twinning, we conducted a genome-wide linkage scan in 525 families using microsatellite and single nucleotide polymorphism marker panels.Non-parametric linkage analyses, including 523 families containing ...

Confined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously
American Journal of Perinatology Reports, 2013 Traditionally, monochorionicity has been regarded as synonymous with monozygosity. However, several recent cases of monochorionic dizygotic twins have shown that monochorionic twins can be dizygous.

Rare spontaneous monochorionic dizygotic twins: a case report and a systematic review [PDF]
BMC Pregnancy and Childbirth, 2022 Background Monochorionic dizygotic twins are a rare condition, mostly related to assisted reproductive technology. This type of twinning is burdened by the same risk of pregnancy complications found in monochorionic monozygotic pregnancies.

Unusual Twinning Resulting in Chimerism: A Systematic Review on Monochorionic Dizygotic Twins
Twin Research and Human Genetics, 2017 Traditionally, it is understood that dizygotic (DZ) twins always have a dichorionic placenta. However, with 8% blood chimerism in DZ twins, placental sharing is probably more common than previously has been recognized. In this article, we will review all

DNA methylation profiles in monozygotic and dizygotic twins
Nature Genetics, 2009 Twin studies have provided the basis for genetic and epidemiological studies in human complex traits1, 2. As epigenetic factors can contribute to phenotypic outcomes, we conducted a DNA methylation analysis in white blood cells (WBC), buccal epithelial ...

Nature Communications, 2018 Zika virus (ZIKV) infection can cause congenital Zika syndrome (CZS), but the underlying mechanisms are poorly understood. Here, the authors generate neural progenitor cells from dizygotic twins with a discordant phenotype regarding CZS and study their ...

Risk for multiple sclerosis in dizygotic and monozygotic twins
Multiple Sclerosis, 2005 We investigated the risks of twins for multiple sclerosis (MS). Our data are linked registers of all Danish twins and of all Danes born between 1920 and 1970 in whom MS was diagnosed before 1997.

Twins and their friendships: Differences between monozygotic, dizygotic same-sex and dizygotic mixed-sex pairs [PDF]
, 2006 This study examined the influence of twin status (monozygotic [MZ], dizygotic same-sex [DZss] and dizygotic opposite-sex [DZos]) on friendship patterns. It examined the friendships of 60 children from 30 twin pairs, mean age 8 years, 4 months.

Handedness in twins: meta-analyses
BMC Psychology, 2022 Background In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii)
