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.
Jake and Jill are twins but they are fraternal twins, not identical twins.
