Q. Which one of the following events is not observed in mitosis?

Solution:

Mitosis is a type of cell division [Also called multiplication division, it helps in growth and repair] that results in the formation of two daughter cells that have the same no. of chromosomes as that of the parent cell. This process does not involve linkage and crossing over. The linkage and crossing over between homologous chromosomes [Also called genetic recombination] is observed in Prophase-1 of Meiosis [Also called Reduction division that results in the formation of gametes]. Hence there is no exchange of genetic material between the homologous chromosomes during meiosis.
