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.
Crossing Over. During meiosis, when homologous chromosomes are paired together, there are points along the chromosomes that make contact with the other pair. This point of contact is deemed the chiasmata, and can allow the exchange of genetic information between chromosomes.This further increases genetic variation.uring meiosis, when homologous chromosomes are paired together, there are points along the chromosomes that make contact with the other pair.
