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?

A. DNA content is halved in both meiosis I and meiosis I. Ploidy level changes from diploid to haploid only in meiosis II.
B. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid only in meiosis II.
C. DNA content is halved in both meiosis I and meiosis Il. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis lI.
D. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.
E. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.

Answer:

option d

Explanation:

Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.

The answer is D. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.
