Question

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 1

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.
