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 I?
A) DNA content is halved in both meiosis I and meiosis I. Ploidy level changes from diploid to haploid only in meiosis
B) DNA content is halved only in meiosis !. 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 !, and remains haploid in meiosisI.
E) DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis I

Answer 1

Answer:

The correct answer is option 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 ".

Explanation:

Meiosis I and meiosis II are two key steps of meiosis, the process at which sex cells are produced. DNA content is halved in both meiosis I and meiosis Il, these two steps are known as the two meiotic divisions.  Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis lI , because the four sex cells produced from meiosis have half the DNA content of a somatic cell.
