Yes, fraternal twins can be one boy and one girl. Fraternal twins result from the fertilization of two separate eggs by two separate sperm cells. This means they can be of different sexes, have different physical appearances, and even possess distinct genetic characteristics. Fraternal twins are as genetically similar as any other pair of siblings.
