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.
Meiosis is the type of cell division that produces both male and female gametes. Spermatogenesis is the production of male gametes, and oogenesis is the production of female gametes. For both types of gametes, meiosis serves to halve the number of chromosomes so that upon fertilization the offspring has the requisite number of chromosomes.
