Multiple Choice
In meiosis, how many successive nuclear divisions occur to produce haploid cells from a diploid cell?
A
Four divisions (two mitotic divisions followed by two meiotic divisions)
B
Three divisions (meiosis I, II, and III)
C
Two divisions (meiosis I and meiosis II)
D
One division (a single meiosis)
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 cell.
Recall that meiosis consists of two successive nuclear divisions: meiosis I and meiosis II, each with distinct phases (prophase, metaphase, anaphase, telophase).
Recognize that meiosis I is the reductional division where homologous chromosomes separate, reducing the chromosome number from diploid to haploid.
Note that meiosis II is similar to mitosis, where sister chromatids separate, resulting in four haploid daughter cells.
Conclude that the total number of successive nuclear divisions in meiosis to produce haploid cells from a diploid cell is two: meiosis I and meiosis II.
