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.
Sexual reproduction is a source of genetic variation. Recombination of chromosomes during meiosis allows for the exchange of DNA, also known as independent assortment. Random â¦segregation also plays a role, as well as some mutations to change the phenotype within different offspring.
