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.
The exchange of a segment of DNA between two homologous chromosomes during meiosis leading to a novel combination of genetic material in the offspring.rossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
