Answer:
Meiosis results in gametes that are used in reproduction.
Explanation:
- <em>The sperm and egg have twice as many chromosomes as the parental cells</em>. INCORRECT. Sperm and eggs are the gametes, and they have only half the number of chromosomes that can be found in the germ cells or somatic cells. Gametes are haploid, n.
- <em>Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division</em>. INCORRECT. The term "daughter cells" is used to refer to the products of cell division. "son cells" is not used at all.
- <em>Meiosis results in gametes that are used in reproduction. </em>CORRECT. Germ cells are the reproductive, diploid cells produced by testes and ovaries. After meiosis, each germ cell produces four haploid cells that are the gametes. Gametes´ destiny is to merge during fecundation, creating a new diploid cell called the zygote. The zygote is a diploid cell that suffers successive mitosis to form the new organism.
- <em>Asexual reproduction requires the production of eggs and sperm. </em>INCORRECT. Only sexual reproduction needs gametes. Cells that reproduce asexually duplicate their genetic material and cytoplasmic content and then divide, producing a new cell identical to its parental. This is the case of binary fission, for example.
