  • Meiosis

    A type of cell division that takes place in germ cells to produce haploid gametes.

  • Crossing Over

    A process in which homologous chromosomes will exchange genetic material with one another; results in genetic variability.

  • Disjunction

    Occurs in meiosis II when homologous chromosomes are separated resulting in gametes with a haploid number of chromosomes.
