Show Answer
Answer:
Correct Answer: A
Solution:
The reduction of DNA content does not occur in meiosis-I.
Truely haploid nuclei in terms of DNA contents as well as chromosomes number are formed in meiosis-II.
When the chromatids of each chromosome are separated in to different nuclei.
Thus meiosis-II is necessary.
