WebCrossing over occurs during prophase I of meiosis I. It involves the switching of genes between homologues non-sister chromatids which allows the mixture of maternal and paternal genetic material with new, recombinant chromosomes. What is the difference between meiosis 1 and meiosis 2? WebExchange of chromosome segments between homologues at the beginning of meiosis. increases genetic variation in offspring. After crossing-over occurs, the chromosome arms tend to separate but remain attached at a site of crossover. This connection is called a (n) chiasma.
