Detailed explanation-1: -Meiosis II results in four haploid daughter cells, each with the same number of chromosomes. However, each chromosome is unique and contains a mix of genetic information from the maternal and paternal chromosomes in the original parent cell.
Detailed explanation-2: -Meiosis II The end result is production of four haploid cells (n chromosomes, 23 in humans) from the two haploid cells (with n chromosomes, each consisting of two sister chromatids) produced in meiosis I. The four main steps of meiosis II are: prophase II, metaphase II, anaphase II, and telophase II.
Detailed explanation-3: -Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.
Detailed explanation-4: -The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
Detailed explanation-5: -During meiosis, a diploid germ cell undergoes two cell divisions to produce four haploid gamete cells (e.g., egg or sperm cells), which are genetically distinct from the original parent cell and contain half as many chromosomes.
