Phenotypically concordant and discordant monozygotic
twins display different DNA copy-number-variation profiles Am J Hum Genet 2008;82: 763-771.
Angiographic findings in monozygotic
twins with coronary artery disease.
Genome, epigenome and RNA sequences of monozygotic
twins discordant for multiple sclerosis.
1986) Aerobic performance in brothers, dizygotic and monozygotic
In fact, they found coronary flow rate was significantly lower in dizygotic twins with a history of major depression compared to their fraternal twins without major depression, but there was no significant flow rate difference between monozygotic
twins discordant for the disorder.
While both genetics and environment have a role to play in the relationship between height and cognition, environmental factors appear to be responsible for two-thirds of the height-intelligence correlation, according to research conducted on cross-trait (height and intelligence), cross-twin correlations between monozygotic
and dizygotic twin pairs.
The potentiality view contends that, even though a fertilized human egg (zygote) may not be an individual human being (since the possibility of monozygotic
twinning exists during 2 weeks after fertilization), it is still a potential human being.
The investigation involved more than 4,000 monozygotic
and dizygotic twins, aged 22-27 years (average age 25), who were enrolled in a population-based longitudinal twin study.
Conjoined twins are rare variants of monozygotic
The team compared the methylation patterns of twins from monozygotic
pairs--twins created when a single embryo splits.
Here we present a familial form of VVS in monozygotic
twins and their parents.
