Detailed explanation-1: -Meiosis is a special process of reductional cell division; it results in the formation of four gametes containing half (1N) the number of chromosomes found in somatic cells. Haploid gametes unite at fertilization to create a diploid zygote.
Detailed explanation-2: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
Detailed explanation-3: -In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis.
Detailed explanation-4: -Telophase II and cytokinesis: This is the last phase of meiosis, however cell division is not complete without another round of cytokinesis. Once cytokinesis is complete there are four granddaughter cells, each with half a set of chromosomes (haploid): in males, these four cells are all sperm cells.
Detailed explanation-5: -III. Spermatogenesis produces four haploid sperm cells from each diploid precursor cell, while oogenesis produces one egg cell and two or more polar bodies.
