What occurs during metaphase II of meiosis?
A
Sister chromatids align at the cell's equator.
B
Homologous chromosomes pair up at the cell's equator.
C
Chromosomes condense and become visible.
D
The nuclear envelope re-forms around each set of chromosomes.
Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells. It consists of two stages: meiosis I and meiosis II.
Recall that metaphase II is a stage in meiosis II. During this phase, the chromosomes are already condensed and visible from the previous stages.
In metaphase II, the key event is the alignment of sister chromatids at the cell's equator. This is similar to metaphase in mitosis, but it involves haploid cells.
Recognize that homologous chromosomes were separated during meiosis I, so they do not pair up at the equator during metaphase II. Instead, it is the sister chromatids that align.
Note that the nuclear envelope re-forms around each set of chromosomes during telophase II, not metaphase II. This is an important distinction in the stages of meiosis.
