Question

Process by which chromosomes exchange materials

Options
  • A

    Meiosis

  • B

    Mitosis

  • C

    Fertilization

  • D

    Mutation

  • E

    Crossing-over

Explanation

Crossing-over occurs during meiosis, specifically during prophase I of meiosis I. It involves the exchange of genetic material between homologous chromosomes, resulting in genetic diversity among the offspring. This process contributes to the variation seen in sexually reproducing organisms.
