B

synthesis of DNA and centromeres

C

D

separation of chromatids

Text Solution

Verified by Experts

The correct Answer is:
D
Meiosis - II is homotypic or equational division similar to mitosis but occurs in haploid nuclei. Meiosis-II is essential to separate out the chromatids of diad chromosomes to bring real haploidy in amount of DNA. It also increases the number of daughter cells though the chromosome number remains the same in daughter cells as produced after meiosis-I.
