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.
Mitosis is the method by which the somatic cells of all multicellular organisms multiply (it is the process by which growth occurs). In addition, plants produce gametes by mitosis (they make spores by meiosis). Animals produce gametes via meiosis. The stages of mitosis are detailed on the pages to come.
