Multiple Choice
In meiosis, how many rounds of cell division occur to produce haploid cells from a diploid precursor?
A
Four rounds of cell division
B
Two rounds of cell division
C
Three rounds of cell division
D
One round of cell division
Verified step by step guidance1
Understand that meiosis is a specialized type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid precursor.
Recall that meiosis consists of two main stages: Meiosis I and Meiosis II, each involving a round of cell division.
In Meiosis I, homologous chromosomes separate, reducing the chromosome number from diploid to haploid, but each chromosome still consists of two sister chromatids.
In Meiosis II, the sister chromatids separate, similar to mitosis, resulting in four haploid cells from the original diploid cell.
Therefore, the total number of cell division rounds in meiosis is two, which leads to the production of haploid cells.
