GED Science Practice Test: Summary – Cell Cycle

Binary fission and mitosis are forms of asexual reproduction that result in daughter cells genetically identical to each other and the parent cell.  Mitosis also plays a role in replacing aging cells, which is not considered “reproduction,” but rather replacement. Meiosis, however, is a form of sexual reproduction, resulting in haploid gametes that combine to form cells which are not identical to either the mother or the father.  Sexual reproduction allows for a mixing of genetic information, which leads to an increase in the genetic variability of a population of organisms.
