Question

Crossing-over occurs during meiosis but not during mitosis because chromosomes only replicate prior to meiosis. in mitosis the replicated chromosomes do not consist of connected chromatids so crossing-over is not possible. homologous chromosomes pair during meiosis but not during mitosis. crossing-over only happens during the second round of cell division and mitosis has only one round of division.

          Crossing-over occurs during meiosis but not during mitosis because
chromosomes only replicate prior to meiosis.
in mitosis the replicated chromosomes do not consist of connected
chromatids so crossing-over is not possible.
homologous chromosomes pair during meiosis but not during mitosis.
crossing-over only happens during the second round of cell division and
mitosis has only one round of division.

Crossing-over occurs during meiosis but not during mitosis because chromosomes only replicate prior to meiosis. ☐ in mitosis the replicated chromosomes do not consist of connected chromatids so crossing-over is not possible. Ohomologous chromosomes pair during meiosis but not during mitosis. ☐ crossing-over only happens during the second round of cell division and mitosis has only one round of division.
