A *fraternal twin*, also known as a *dizygotic twin*, is what happens when two separate eggs are fertilized by two separate sperm. Basically, they're just siblings who happen to be born at the same time. 👯 They share about 50% of their genes, just like any other brother or sister. They can be the same sex or different sexes. Think of them as siblings who shared the womb. They are as genetically similar as normal siblings, not identical copies.
The term *fraternal* comes from the Latin word *frater*, meaning 'brother.' It highlights the sibling relationship between the twins. *Twin* comes from the Old English *twinn*, meaning 'two together.' So, *fraternal twin* emphasizes that they are related as siblings. It indicates that they are not genetically identical, unlike identical twins.
In *Harry Potter*, Fred and George Weasley are classic *fraternal twins*. They're brothers who happen to be twins, causing chaos and fun wherever they go. They look alike, but they're not identical, and their personalities are distinct. They exemplify the kind of bond and mischief that *fraternal twins* often share.
