Detailed explanation-1: -Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Detailed explanation-2: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Detailed explanation-3: -In women, only one of the four sex cells becomes an egg cell that can be fertilized. During meiosis, it receives most of the cell body of the parent cell. The three smaller cells – referred to as polar bodies – break down and disappear. If a sperm cell fertilizes an egg cell, the nuclei of the two cells combine.
Detailed explanation-4: -The remaining chromosomes are captured and aligned by the second meiotic spindle. At this stage, the cell is called an egg and awaits fertilisation.
