Question

multiple choice question

in ______, sister chromatids separate and become single chromosomes in haploid cells.

o meiosis ii
o meiosis i
o mitosis
o interphase

Explanation:

1. Analyze meiosis I: In meiosis I, homologous chromosomes separate, not sister chromatids. So this option is incorrect.
2. Analyze mitosis: Mitosis occurs in somatic cells and results in diploid daughter cells, not haploid cells. So this option is incorrect.
3. Analyze interphase: Interphase is a preparatory phase for cell division, not a phase where sister chromatids separate. So this option is incorrect.
4. Analyze meiosis II: In meiosis II, sister chromatids separate, and since the cells are already haploid (after meiosis I), this process happens in haploid cells.

Answer:

A. meiosis II
