If a eukaryotic cell has 20 chromosomes and it undergoes meiosis ii, how many cells will result, and how many chromosomes will they contain?

Four cells and 10 chromosomes each. Before going through meiosis ii it has to go through meiosis i (homologous chromosomes separate) first to form two cells. Then both cells goes through meiosis ii (sister chromatids separate) to form two cells each. Therefore 4 cells.
