WebMonozygotic twins (identical twins) arise from the division of a single fertilized egg.

WebBut identical twins, or monozygotic twins, share 100% of their DNA, whereas dizygotic twins share only 50% of their DNA. They share the same as siblings. And so if there are things that are more concordant or more similar in monozygotic twins than in dizygotic twins, the usual conclusion is that genetics plays a role in that similarity. WebSome concerns are: 1. Low birth weight. Birth weight is a factor for nearly all monochorionic twins. All twins are 10 times more likely to have a lower birth weight than babies from single pregnancies are. For monochorionic twins, the risk of low birth weight is four times higher than in pregnancies in which each fetus has its own placenta. 2. fishing venues in shropshire
