Question

Quizplus · Accepted Answer

The separation of cells at the two-cell stage following fertilization leads to the production of identical twins. These twins are genetically identical because they originated from the same fertilized egg. Thus, choice A is the best option. Fraternal twins, on the other hand, come from two separate eggs fertilized by different sperm cells, thus they are genetically different. Dizygotic twins are also fraternal twins, but they are formed when two separate ova are fertilized by two different sperm cells. They may or may not be of the same sex. Therefore, choices B, C, and D are not the best options in this case.
