Detailed explanation-1: -The process of mitosis ensures that each daughter cell has a copy of every chromosome present in the parent cell. What is the use of this process? All the cells divide into two daughter cells and each daughter cell has the same number of chromosomes.
Detailed explanation-2: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes.
Detailed explanation-3: -The process of mitosis ensures that each daughter cell receives a full complement of chromosomes.
Detailed explanation-4: -Cytokinesis. Cytokinesis is the second part of the mitotic phase during which cell division is completed by the physical separation of the cytoplasmic components into two daughter cells.
Detailed explanation-5: -Meiosis also produces genetic variation by way of the process of recombination. Later, this variation is increased even further when two gametes unite during fertilization, thereby creating offspring with unique combinations of DNA.
