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.
Reproduction â the process by which organisms make more organisms like themselves â is one of the things that set living things apart from nonliving matter. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes (pronounced: GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. The female needs a male to fertilize her egg, even though it is she who carries offspring through pregnancy and childbirth. When the sperm fertilizes, or meets, the egg, this fertilized egg is called the zygote.
