Detailed explanation-1: -Both mitosis and meiosis involve cell division. Both the processes occur in the M-phase of the cell cycle. In both cycles, the typical stages are prophase, metaphase, anaphase and telophase. In both cycles, synthesis of DNA takes place.
Detailed explanation-2: -Meiosis starts with a diploid (2n) parent cell that divides to make 4 haploid (n) cells. In sexual reproduction, haploid gametes from two different individuals combine to produce a diploid zygote. The resulting offspring is genetically different from both parents.
Detailed explanation-3: -Typically, this type of cell division occurs in the body’s somatic cells. Therefore, the parent cell in mitosis starts off as diploid. Since mitotic cell division results in the formation of new cells which are clone to the parental cell, the resulting daughter cells at the end of mitosis are diploid.
