Meiosis II performs:
Correct answer: D. Separation of chromatids
- A. Separation of sex chromosomes
- B. Synthesis of DNA and centromere
- C. Separation of homologous chromosomes
- D. Separation of chromatids
Explanation
Meiosis II is shorter than the typical mitotic division because of the shortening of the prophase of this division. The division maintains the number of chromosomes produced at the end of the reduction division. Hence, it is called homotypic or equational division, though it is similar to mitosis. The main function of homotypic division or meiosis II is to separate the chromatids of univalent chromosomes which differ from each other in their linkage groups due to crossing over.
