What happens if two twins have a baby?

Can you have identical twins with two placentas?

Because fraternal, or dizygotic, twins are 2 separate fertilized eggs, they usually develop 2 separate amniotic sacs, placentas, and supporting structures. Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into 2.

What happens if identical twins have a baby with identical twins?

Can DNA tests tell twins apart?

Do identical twins have 100% the same DNA?

Identical twins form from the same egg and get the same genetic material from their parents — but that doesn’t mean they’re genetically identical by the time they’re born.
