The NCAA has instituted strict guidelines for eligibility under medical exceptions for banned substances, including stimulants used to treat ADHD/ ADD, medications for male-pattern baldness, peptide hormones (hGH), and anabolic steroids (testosterone) or any other medications banned* by the NCAA.
Meiosis also differs from mitosis in that it involves a process known as recombination, during which chromosomes exchange segments with one another. As a result, the gametes produced during meiosis are genetically unique.
In order to reach that objective successfully, the sexual reproduction is instrumental, and the gametes from males and females are mixed with each other to produce offspring. Spermatogenesis is the basic mean of producing the male gametes, and spermiogenesis is a stage of the main process of production.
