crossing over
crossing over An exchange of portions of chromatids between
homologous chromosomes. As the chromosomes begin to move apart at the end of the first prophase of
meiosis, they remain in contact at a number of points (see
chiasma). At these points the chromatids break and rejoin in such a way that sections are exchanged (see illustration). Crossing over thus alters the pattern of genes in the chromosomes. See
recombination.
