Question

which of the following best describes the process of meiosis? *
a process that results in the repair and replacement of damaged cells within the body.
a type of cell division that produces four genetically unique haploid cells, called gametes.
a type of cell division that produces two identical diploid daughter cells, called gametes.
a cycle of cell growth and dna replication without any division

Explanation:

Meiosis is a specialized cell - division process. It occurs in germ cells. The key characteristics are: it has two rounds of division (meiosis I and meiosis II), and it results in the formation of four haploid cells. These haploid cells (gametes) are genetically unique due to processes like crossing - over (during prophase I) and independent assortment (during metaphase I).

• Option 1: The repair and replacement of damaged cells is the function of mitosis, not meiosis.
• Option 3: Producing two identical diploid daughter cells is a feature of mitosis. Also, gametes are haploid, not diploid.
• Option 4: A cycle of cell growth and DNA replication without division is not meiosis. Meiosis involves division.

Answer:

B. A type of cell division that produces four genetically unique haploid cells, called gametes.
