Meiosis Practice Test

During meiosis in a diploid cell, tetrads form and then align at the metaphase plate. The student notes that each homolog in a tetrad is attached to spindle fibers from opposite poles, while sister chromatids of each homolog share attachment to the same pole. Which outcome is most likely when the cell transitions into anaphase I?

In a diploid cell with $2n=6$, homologous chromosome pairs align at the metaphase plate during meiosis I. In one observed cell, all three maternal homologs face the same pole while all three paternal homologs face the opposite pole. The cell completes meiosis I and then meiosis II normally, with sister chromatids separating in meiosis II. Which outcome is most likely for the chromosome sets in the four gametes produced from this single cell?
