Twins from different eggs are fraternal twins. They are siblings with the same birthdate. They are twins, but not identical, and can even be girl and boy. It is the same process taking place as a single child that a woman becomes pregnant with, but the process happens with two children at the same time. The woman releases two eggs that month instead of one, and they both are fertilized. That is how this type of twin is produced.

There are other joining bands, also. The Girls can be beautiful
