they can... it is possible and has happened before but its VERY VERY unlikly. so ussually no
do identical or non identical twins share the same placenta
Looks......?
That depends on the type of twins. Fraternal twins usually have separate amniotic sacs. Identical twins usually share the amniotic sac.
No, because identical twins which share identical genes have distinct fingerprints.
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
If they share a brain then they only have one set of thoughts.
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.
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.

Yes, Rex and Rob Ryan are identical twins. They both have similar physical features and share the same DNA.
