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