Question

question 31
before which stage(s) of meiosis is dna replicated?
only before meiosis i
before meiosis 1 and again before meiosis ii
only after meiosis i and before meiosis ii
question 32
a diploid cell undergoes both meiosis i and meiosis ii. what are the p division?
four haploid cells genetically distinct from the parent cell
four diploid cells genetically distinct from the parent cell
four haploid cells genetically identical to the parent cell
two haploid cells genetically distinct from the parent cell

Explanation:

• Question 31: In meiosis, DNA replication occurs only once, which is before Meiosis I (during the interphase of Meiosis I). There is no DNA replication before Meiosis II.
• Question 32: A diploid cell undergoes meiosis (Meiosis I and Meiosis II). Meiosis I is a reduction - division (homologous chromosomes separate), and Meiosis II is similar to mitosis (sister chromatids separate). The result is four haploid cells. Also, due to crossing - over (during prophase I of Meiosis I) and independent assortment (during metaphase I of Meiosis I), the daughter cells are genetically distinct from the parent cell.

Answer:

• Question 31: Only before Meiosis I
• Question 32: four haploid cells genetically distinct from the parent cell
