Guida verificata passo dopo passo1
Understand that meiosis consists of two distinct rounds of cell division, called meiosis I and meiosis II.
Recognize that each round of meiosis includes the full sequence of phases: prophase, metaphase, anaphase, and telophase (PMAT).
In meiosis I, homologous chromosomes are separated, and the cell goes through PMAT once.
In meiosis II, the sister chromatids are separated, and the cell again goes through PMAT a second time.
Therefore, the cell undergoes the PMAT sequence two times during meiosis.
