Meiosis II is necessary because:
Show answer and explanation
Correct answer: It separates sister chromatids left joined after DNA replication
After Meiosis I, each cell is haploid but its chromosomes still consist of two sister chromatids. Meiosis II separates these chromatids so each of the four resulting gametes carries a single copy of each chromosome.
