Question

distinguish between equational division and reduction division

Answer 1

Mitosis is also known as equational division and meiosis is also called as reductional division.1.Mitosis takes place within somatic cells (cells that make up the body).Meiosis takes place within gamete cells.2.One single division of the mother cell results in two daughter cells.Two divisions of the mother cell result in four meiotic products or haploid gametes.3.A mitotic mother cell can either be haploid or diploid.A meiotic mother cell is always diploid.4.The number of chromosomes per nucleus remains the same after division.The meiotic products contain a haploid (n) number of chromosomes in contrast to the (2n) number of chromosomes in mother cell.5.It is preceded by a S-phase in which the amount of DNA is duplicated.In meiosis, only meiosis I is preceded by a S-phase.6.In mitosis, there is no pairing of homologous chromosomes.During prophase I, complete pairing of all homologous chromosomes takes place.7.There is no exchange of DNA (crossing-over) between chromosomes.There is at least one crossing-over or DNA exchange per homologous pair of chromosomes.8.The centromeres split during anaphase.The centromeres do separate during anaphase II, but not during anaphase I.9.The genotype of the daughter cells is identical to that of the mother cells.Meiotic products differ in their genotype from the mother cell.10.After mitosis, each daughter cell has exactly same DNA strands.After meiosis, each daughter cell has only half of the DNA strands

Answer 2

One of the main difference between the Equational division and the reductional division is that the equational division is a type of division that is used by the unicellular organism for the reproduction. On the other hand, the reductional division is a type of division which is used by the multicellular organism for the reproduction. The equational division is called the process of mitosis while the reductional division is called the process of meiosis.
