How many rounds of cell division occur during meiosis (from one diploid cell to haploid cells)?
A
Four divisions
B
Two divisions (meiosis I and meiosis II)
C
Three divisions
D
One division
검증된 단계별 안내1
Understand that meiosis is a special type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid cell.
Recall that meiosis consists of two main sequential divisions: meiosis I and meiosis II.
Recognize that meiosis I is the reductional division where homologous chromosomes separate, reducing the chromosome number from diploid to haploid.
Know that meiosis II is the equational division where sister chromatids separate, similar to mitosis, but it does not change the chromosome number further.
Conclude that since meiosis involves these two distinct rounds of division, the total number of cell divisions during meiosis is two.
