Question

The parent cell that enters meiosis is diploid, whereas the four daughter cells that result are haploid. Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis I and meiosis II? (Note: Ignore any effects of crossing over.) View Available Hint(s) Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis I and meiosis II? (Note: Ignore any effects of crossing over.) DNA content is halved in both meiosis I and meiosis II. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II. DNA content is halved in both meiosis I and meiosis II. Ploidy level changes from diploid to haploid only in meiosis II. DNA content is halved only in meiosis II. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid only in meiosis I

Answer 1

Answer:

DNA content is halved in both meioses I and meiosis II. Ploidy level changes from diploid to haploid only in meiosis II.

Explanation:

In meiosis, one diploid cell produces four haploid cells.  At the end of meiosis I, just like in mitosis, we will have two diploid daughter cells and then these two cells undergo cellular division again. In this secondary division, more precisely in the anaphase II, the centromere divides (this process does not happen in the meiosis I anaphase I, where homologous chromosomes move together to opposite poles) and sister chromatids move to opposite poles, leaving four individual cromatids following a cytoplasmatic division forming four new haploid cells.
