Some legitimate medications contain NCAA banned substances, and student-athletes may need to use these medicines to support their academics and their general health. The NCAA has a procedure to review and approve legitimate use of medications that contain NCAA banned substances through a medical exceptions procedure. The benefit of a medical exception procedure is that in most cases the student-athleteâs eligibility remains intact during the process.
So, when the chromosomes go on to meiosis II and separate, some of the daughter cells receive daughter chromosomes with recombined alleles. Due to this genetic recombination, the offspring have a different set of alleles and genes than their parents do.
Mutations can also happen in sexually reproducing species to further add to the diversity of the offspring. The process of meiosis, which creates the gametes used for sexual reproduction, has built in ways to increase diversity as well. This includes crossing over, which ensures the resulting gametes are all different genetically.
