How does mitosis differ from meiosis?
Mitosis is a nuclear division consisting of cytokinesis producing two identical daughter cells while in the stage of prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis is used for most cell division by adding new cells during development and replacing old cells. This process consists of the creation of daughter cells, which are genetically identical to their mothers without one more chromosome or one less (Biology, 2016). However, Meiosis involves the creation of gametes (sex cells or sperm and eggs). This process involves producing daughter cells with half as many chromosomes as the starting cell. It is a division method, which takes us from a diploid cell (one with two sets of chromosomes) …show more content…

This prevents the sperms from mixing with semen. The testicles continue creating sperm, however, the body reabsorbs it by testis. The vas deferens blocks the prostate and seminal vesicles. It typically takes a few months for all the remaining sperms to become reabsorbed after a vasectomy. Extra precautions of using other methods of birth control are suggested until a sample can be tested indicating the sperm count being at zero. There are no significant proofs that a vasectomy decreases testosterone, however recent studies have indicated that an autoimmune disease is linked to vasectomies may occur as the body reacts to sperms as a foreign invader. Generally followed by infiltration of immune cells and the sperm found in the testes are destroyed resulting of the testosterone producing cells being destroyed as well (Family Doctor, …show more content…

Each main spermatocyte is divided into two secondary spermatocytes and each being divided into two spermatids resulting in it developing into mature spermatozoa known as sperm cells. The main spermatocyte offers a rise to two cells (secondary spermatocytes and the two secondary spermatocytes) through their subdivision creating four spermatozoa. Spermatozoa are mature male gametes found in many sexually reproducing organisms and known as the male version of gametogenesis resulting in the formation of spermatocytogenesis, a diploid spermatogonium residing in the basal compartment of seminiferous tubules that are divided mitotically to create two diploid intermediate cells known as primary spermatocytes. Spermatogenesis are very dependent on optimal conditions for the process to correctly happen and vital for sexual reproduction. It begins at puberty as the sperm count increases with age. However, each main spermatocyte moves into the adluminal compartment of the seminiferous tubules duplicating it DNA resulting in undergoing meiosis allowing it to create two haploid secondary spermatocytes that later divide again in to haploid spermatids. However, during division a random inclusion of parental chromosome and chromosomal cross over both increasing the genetic variability of the gamete. Although, each cell division from a spermatogonium to a spermatid are incomplete
