In the past, twins have been studied to determine the genetic contribution to various disease processes. Recent work, however, suggests that monozygotic (MZ) twins are not truly identical. Many genetic forms of discordance have been described within MZ twin pairs and may even play a role in causing MZ twinning. ...

Monochorionic monozygotic twins frequently suffer complications from the presence of vascular anastomoses in their monochorionic placentas. Also, sharing of perfusion zones may be unequal, leading to marked growth discordance. This paper analyzes four measures of perinatal outcome (gestational age at delivery, perinatal mortality, birth weight discordance, and presence/absence of hydramnios) ...
Bamforth F - - 1996
Patterns of X-chromosome inactivation in chorion, amnion, and cord from 79 pairs of twins were examined. Seven sets of triplets were included in the analysis, both as twin pairs and triplets. Twins were stratified as dizygotic (DZ), monozygotic (MZ), monochorionic, and dichorionic and were selected for birth weight discordance, discordance ...
