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 a process by which we can halve the number of chromosomes. It takes place whenever the organism has to produce daughter cells that have half the number of chromosomes as the parent cells. In humans, meiosis occurs in spermatogonial and oogonial cells to produce sperms and eggs respectively. In higher plants which have a dominant diploid sphorophytic phase, the gametophytic phase is produced by meiosis. Meiosis occurs in almost all the higher living organisms.
