검증된 단계별 안내1
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.
Recognize that telophase I is a phase within meiosis I. During this phase, the cell undergoes several changes to prepare for the next stage of division.
During telophase I, the nuclear membrane reforms around each set of chromosomes. This is a key event that distinguishes telophase I from other phases.
Note that at the end of telophase I, each daughter cell contains a haploid set of chromosomes, each consisting of two sister chromatids.
Understand that telophase I is followed by cytokinesis, where the cytoplasm divides, resulting in two separate cells, each ready to enter meiosis II.
