One type of genetic engineering that is extremely controversial is cloning. Which of the following statements accurately describes an aspect of this process?

B. A clone is an organism produced asexually from a cell from each of the parents.
C. A clone is genetically identical to the parent.
D. Fraternal twins are clones.
E. Identical twins are not clones.
C. A clone is genetically identical to the parent.
A clone is an organism grown from a single cell of the parent, and thus is genetically identical to the parent. In other words, the genes and chromosomes found in each cell's nucleus are the same in clone and parent. Identical twins are clones. So are all the cells in our bodies except for eggs and sperm.
