Quizplus · Accepted Answer

Crossing over is the process in which there is an exchange of genetic material between homologous chromosomes that occurs during meiosis. This exchange helps to increase genetic diversity in the offspring. Karyotyping is a process of looking at the number and appearance of chromosomes under a microscope, while concordance is a measure of how often two traits or disorders occur together in a population. Cloning is the process of creating genetically identical copies of an organism. None of these choices accurately describe the process of genetic exchange during meiosis, making crossing over the best choice.
