Detailed explanation-1: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-2: -In this simple example, a diploid body cell contains 2n = 2 chromosomes. One chromosome came from mom and one from dad. In humans, 2n = 46, so 23 came from mom, and 23 from dad.

Detailed explanation-3: -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-4: -During meiosis, the ploidy is reduced from diploid (2n) to haploid (1n) in production of eggs and sperm. With the successful union of egg and sperm, the normal diploid (2n) complement of chromosomes is restored.
