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.
Gamete production is the main job of a gametophyte. Gametes are haploid reproductive cells, such as eggs and sperm. They are produced in sex organs on the haploid gametophyte by mitosis, or cellular division without reduction of chromosome sets.
