Final answer:
In meiosis II, there should be 7 individual chromosomes, not tetrads, on the metaphase plate because the diploid number is 14 and tetrads do not form during meiosis II.
Step-by-step explanation:
If the diploid number of chromosomes in a cell is 14, this means there are 7 pairs of homologous chromosomes. In meiosis I, homologous chromosomes separate, and tetrads (pairs of homologous chromosomes) are present on the metaphase plate. However, by the time a cell reaches meiosis II, the tetrads have already been separated into individual chromosomes during anaphase I of meiosis and do not form tetrads in meiosis II.
Therefore, in meiosis II, we expect to see individual chromosomes, not tetrads, aligning on the metaphase plate. Since each of the now haploid cells formed at the end of meiosis I contains 7 chromosomes, there should be 7 individual chromosomes lining up at the metaphase plate during metaphase II, ready to be separated into sister chromatids.
