A pair of twins born at the same time, fertilized by two different sperm. Fraternal twins can be boy-girl, boy-boy, or girl-girl. Fraternal twins normally dont look the same, as identical twins do. But fraternal twins do share alot of the same bonds, as identical twins.

("fraternal"), meaning that each twin develops from two different eggs and each egg is fertilized by its own sperm cell. We can be passed as best friends even though we are fraternal twins. We are basically siblings but we are the same age so its different we share such a strong bond we hang out all the time.
