Question

Quizplus · Accepted Answer

Clones are genetically identical to the parent, which is the defining feature of cloning. A is incorrect as egg and sperm cells are not organisms, they are reproductive cells. B is incorrect as a clone can be produced asexually, but not necessarily from a cell from each parent. D is incorrect as fraternal twins come from two separate eggs fertilized by two separate sperm cells, so they are not clones. E is incorrect as identical twins are clones, as they come from the same fertilized egg that split into two embryos.
