Detailed explanation-1: -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.

Detailed explanation-2: -Meiosis starts with a diploid (2n) parent cell that divides to make 4 haploid (n) cells. In sexual reproduction, haploid gametes from two different individuals combine to produce a diploid zygote. The resulting offspring is genetically different from both parents.

Detailed explanation-3: -During meiosis I, the cell is diploid because the homologous chromosomes are still located within the same cell membrane. Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid.

Detailed explanation-4: -At the beginning of meiosis II, the cells are diploid. In meiosis I, reduction division occurs, and half chromosomes are distributed into two daughter cells. These daughter cells are haploid. These daughter cells undergo meiosis II and divide mitotically.
