Prophase I

Detailed explanation-1: -The cells that enter meiosis II are the ones made in meiosis I. These cells are haploid-have just one chromosome from each homologue pair-but their chromosomes still consist of two sister chromatids . In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.
Detailed explanation-2: -Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid. Following this first division, the cell begins meiosis II with prophase II, making this the first haploid meiotic stage.
Detailed explanation-3: -However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
