What is meant by fraternal twins?

Because fraternal, or dizygotic, twins are 2 separate fertilized eggs, they usually develop 2 separate amniotic sacs, placentas, and supporting structures. If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA.

What is the difference between paternal and fraternal?

The main difference in fraternal vs paternal twins is the number of fertilized eggs involved. Fraternal twins develop when two separate sperm cells fertilize two eggs. In contrast, paternal twins develop when one sperm fertilizes one egg; then, after conception, the zygote splits, creating two individual embryos.
