In meiosis, what is the direct outcome of completion of meiosis II for a single cell that entered meiosis I (assuming typical animal meiosis and no nondisjunction)?
A
Four diploid daughter cells produced by separation of homologous chromosomes
B
Two haploid daughter cells in which homologous chromosomes have separated but sister chromatids remain together
C
Two diploid daughter cells that are genetically identical to the parent cell
D
Four haploid daughter cells, each with sister chromatids separated into individual chromosomes
Verified step by step guidance1
Recall that meiosis consists of two sequential divisions: meiosis I and meiosis II. Meiosis I separates homologous chromosomes, and meiosis II separates sister chromatids.
Understand that a single cell entering meiosis I is initially diploid (2n), meaning it has two sets of chromosomes, one from each parent.
After meiosis I, the cell divides into two haploid (n) daughter cells, each containing one chromosome from each homologous pair, but with sister chromatids still joined.
Meiosis II then acts on these two haploid cells, separating the sister chromatids into individual chromosomes, similar to mitosis but starting from haploid cells.
Therefore, the direct outcome of completing meiosis II is four haploid daughter cells, each with individual chromosomes (formerly sister chromatids) separated, resulting in genetic diversity.
