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.)

Answer 1

I think it is when DNA content is halved in both meiosis l and meiosis ll . Ploidy level changes from diploid to haploid in meiosis l , and remains haploid in meiosis ll

Answer 2

Answer:

I snatched this from someone else, so it isn't mine, but I hope it helps. They don't have a username so I cannot credit them.

Explanation:

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.

During anaphase of both meiosis I and meiosis II, the DNA content (number of copies of chromosomes) in a cell is halved. However, the ploidy level changes only when the number of unique chromosome sets in the cell changes. This occurs only in meiosis I (where separation of homologous chromosomes decreases the ploidy level from 2n to n and produces daughter cells with a single chromosome set).
