Which description distinguishes the process of meiosis from mitosis?

-Unlike mitotic cells, meiotic cells undergo a single division to halve their chromosome number,

after which they undergo crossing over to restore their diploid state

-Unlike mitotic cells, meiotic cells undergo multiple divisions to produce an effectively unlimited

array of daughter cells which are genetically identical to the parent cells.

-Unlike mitotic cells, meiotic cells undergo pairing of homologous chromosomes, allowing

centromeres to remain intact throughout both cellular divisions.

-Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for

genetic diversity in sexually reproducing organisms.

    Answer: Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.

    Explanation:

    Both meiosis and mitosis are types of cell division. However, unlike mitosis that occur at one division only and yield two daughter cells with diploid number; meiosis involves two division steps:

    - Meiosis I

    where the parent cell is halved in chromosome number, and genetic materials are mixed between chromatids

    -Meiosis II

    where the two daughter cells generated in meiosis I is further divided into four haploid cells.
