Quizplus · Accepted Answer

Dizygotic or fraternal twins form from two separate eggs fertilized by two separate sperm, resulting in two genetically unique embryos. This is in contrast to monozygotic or identical twins, which form from one fertilized egg that splits into two genetically identical embryos. Gamete and zygote do not accurately describe the type of twins that Evan and Evelyn are.
