What occurs during Prophase II of meiosis?

Chromosomes line up at the equatorial plate.

Homologous chromosomes pair up and exchange segments.

The nuclear envelope breaks down and spindle fibers form.

Sister chromatids are pulled apart to opposite poles.

Verified step by step guidance

Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two stages: Meiosis I and Meiosis II.

Recall that Prophase II is a stage in Meiosis II, which follows Meiosis I. During Meiosis I, homologous chromosomes are separated, resulting in two haploid cells.

In Prophase II, the nuclear envelope that reformed during Telophase I breaks down again, preparing the cell for the next division.

Spindle fibers begin to form from the centrosomes, which have moved to opposite poles of the cell. These fibers are crucial for the movement of chromosomes during cell division.

Unlike Prophase I, there is no pairing of homologous chromosomes or crossing over in Prophase II, as these processes have already occurred in Meiosis I.
