Are the four daughter cells produced from meiosis II diploid or haploid?
A
Diploid
B
Haploid
Verified step by step guidance1
Understand the process of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of four genetically distinct daughter cells.
Recall the stages of meiosis: Meiosis consists of two consecutive divisions, meiosis I and meiosis II. Meiosis I is the reductional division where homologous chromosomes are separated, and meiosis II is the equational division where sister chromatids are separated.
Focus on meiosis II: During meiosis II, the sister chromatids of each chromosome are separated into different cells. This division is similar to mitosis but occurs in haploid cells.
Determine the ploidy of the daughter cells: Since meiosis I already reduced the chromosome number by half, the cells entering meiosis II are haploid. Therefore, the daughter cells produced at the end of meiosis II remain haploid.
Conclude the analysis: The four daughter cells produced from meiosis II are haploid, each containing one set of chromosomes, which is half the number of chromosomes of the original diploid cell.
