It can be either. Sometimes they are in their own individual sac, and in other instances they share one amniotic sac.
do identical or non identical twins share the same placenta
Fraternal twins (dizygotic twins) are simply two fertilized eggs that are implanted in the uterus at the same time. Identical twins (monozygotic twins) is one fertilized egg that separates into two embryos. In most cases, identical twins share one placenta, but have separate amniotic sacs. In some cases, they have two placentas. In rare cases, they share both the placenta and the amniotic sac.
Identical twins can share the same placenta during pregnancy, but it is not always the case. In some instances, identical twins may have separate placentas.
yes they are... simmes twins form from one egg that is in the process of separating into two eggs or identical twins... but the process isn't finished and that is why they are "stuck together"
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
No, twins can either share the same placenta (monochorionic) or have separate placentas (dichorionic), depending on whether they are identical or fraternal twins.
Yes, twins can share the same sac during pregnancy, a condition known as monochorionic monoamniotic twins. This occurs when the twins develop from a single fertilized egg and share both the placenta and the amniotic sac.
Yes, identical twins have the same DNA because they are formed from a single fertilized egg that splits into two embryos. This means they share the same genetic information and are genetically identical.
The difference between Identical and Non-Identical twins is that Identical twins share the same placenta and are basically identical to one another. Non-Identical twins do not share the same placenta in the womb and two eggs fertilized at time of conception as opposed to one egg splitting in the case of Identical twins. I think that covers the basics. Hope this has clarified things for you.
Yes, twins can share a placenta during pregnancy. This occurs when identical twins develop from a single fertilized egg and share the same placenta.
