Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis I and meiosis II?
Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis I and 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 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 only in meiosis I. Ploidy level changes from diploid to haploid only in meiosis II.
