Question

Quizplus · Accepted Answer

Fraternal twins are the result of two separate eggs being fertilized by two separate sperm. Therefore, they are also called dizygotic twins. Identical twins, on the other hand, come from a single fertilized egg that splits into two embryos, so they are called monozygotic twins. Heterozygous refers to individuals who have different versions of a particular gene on their two paired chromosomes, and is not directly related to twin types.
