Question

Quizplus · Accepted Answer

Fraternal twins, also known as dizygotic twins, are produced when two eggs are each fertilized by a different sperm cell. Each fertilized egg will develop its own placenta, resulting in two placentas for the two separate embryos. Therefore, choice B is correct. Fraternal twins are not identical, so choice D is incorrect. While fraternal twins can have the same biological father, they can also have different fathers if the mother ovulated more than one egg and had intercourse with multiple partners, so choice C is incorrect.
