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 <u>(this process does not happen in the meiosis I anaphase I, where homologous chromosomes move together to opposite poles)</u> and sister chromatids move to opposite poles, leaving four individual cromatids following a cytoplasmatic division forming four new haploid cells.
