Detailed explanation-1: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-2: -The organism’s diploid germ-line stem cells undergo meiosis to create haploid gametes (the spermatozoa for males and ova for females), which fertilize to form the zygote.

Detailed explanation-3: -The end products of meiosis are gametes, which are cells with half the chromosome amount of normal cells.

Detailed explanation-4: -Mitosis produces two genetically identical diploid cells, whereas meiosis produces four non-identical haploid cells.

Detailed explanation-5: -The crossed over chromosomes are then segregated into the four haploid cells produced at the end of meiosis. Hence, the four haploid cells are genetically dissimilar.
