Honors Biology- Meiosis Questions and Answers Graded A+ What is the function of the chiasma in meiosis? The chiasma is the point where homologous chromosomes exchange genetic material during crossing over. What occurs during prophase I of meiosis that does not occur in mitosis? During prophase I, homologous chromosomes pair up and form tetrads, which does not happen in mitosis. How is genetic variation achieved through meiosis? Genetic variation is achieved through crossing...
