The ultrasound can determine if they are fraternal or identical. If they are identical then they will share a placenta and they may even share an amniotic sac. If they are fraternal they will have separate placentas. Sometimes it is difficult to see because of the membrane but the ultrasound is sophisticated and they normally can tell.

Why do you think identical twins were more alike than fraternal twins?
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.

What is the difference fraternal and identical twins?
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
Why are the twins identical?
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
