In meiosis, how many times does a single diploid cell divide to produce haploid cells?
A
Three divisions, producing eight haploid daughter cells
B
Two divisions (meiosis I and meiosis II), producing two diploid daughter cells
C
Two divisions (meiosis I and meiosis II), producing four haploid daughter cells
D
One division, producing two haploid daughter cells
검증된 단계별 안내1
Recall that meiosis is a specialized type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid parent cell.
Understand that meiosis consists of two sequential divisions: meiosis I and meiosis II.
In meiosis I, homologous chromosomes are separated, reducing the chromosome number from diploid (2n) to haploid (n), but each chromosome still consists of two sister chromatids.
In meiosis II, the sister chromatids are separated, similar to mitosis, resulting in four haploid daughter cells in total.
Therefore, a single diploid cell undergoes two divisions during meiosis, producing four haploid daughter cells.
