Examples of dizygotic

dizygotic
Concordance rates differed significantly across monozygotic and dizygotic twin pairs for broadly defined self-reported anorexia nervosa and bulimia nervosa.
We report here such a concurrence in dizygotic twins conceived by in-vitro fertilisation.
These studies compare the occurrence of an illness in monozygotic and dizygotic sets of twins.
The marked progression in the dependence of monozygotic, dizygotic and trizygotic rates on maternal age underlines the importance of this factor in multiple birth studies.
Therefore, monozygotic twins should be concordant for inherited traits approximately twice as often as dizygotic twins.
Of the complete pairs, 3269 pairs were monozygotic, 9010 pairs dizygotic, and 128 pairs of unknown zygosity.
However, while there is little variation in the monozygotic twinning rates in most of the regional groups, the dizygotic twinning rates vary considerably.
All the twin pairs thought to be dizygotic were proved to be so with a difference in one or more of the blood groups.
If the twins are dizygotic, there is only a 10% probability that the second twin will develop the disorder.
In the absence of such findings it may be that one link between dizygotic twinning and reproductive potential may simply be high coital rates.
The monozygotic twin sample comprised five male and five female pairs and the dizygotic twin sample three male and three female pairs.
Dizygotic twinning is associated with maternal age and perhaps with social class.
It is generally accepted that the most powerful of the designs is the twin study, using either genetically identical (monozygotic) twins, or fraternal (dizygotic) twins.
Monozygotic twins share 100% of their genes, whereas dizygotic twins share on average only 50%.
Correlations were a little higher in monozygotic twins than dizygotic.
