Briefly describe the difference(s) between cell division as the result of "meiosis" and cell division as the result of "mitosis."
What will be an ideal response?
Meiosis is also referred to as "reduction division.". This means that the 46
chromosomes within the cell nucleus line up into 23 pairs. These 23 pairs then split and
one member from each pair goes to each newly formed cell. Because of this, the
newly formed cells have half the genetic material contained in the original cell. In this
sense, the cells are not identical but share 50 percent genetic similarity. With mitosis,
the identical genetic code is carried into each newly formed cell in the body. In other
words, these cells, when they divide, are identical to the cells that divided to form them.
Cloning results from mitosis. Because the newly formed cells are "replications" of the
preceding cell, there is no genetic variability.
