What would happen to the chromosome number in gametes and offspring if ​gametes were formed by the mitotic process instead of the meiotic process?

As two students, who will be designated Student J and Student K, were studying together, they argued about the differences between Mitosis and Meiosis (both Meiosis I and Meiosis II). Student J maintained that it if they were looking at very good slides under the microscope and concentrated on Metaphase, it would be possible to tell the difference between the cells undergoing Mitosis, the cells undergoing Meiosis I, and the cells undergoing Meiosis II. Student K said it would be impossible to tell which nuclear division was occurring. Assume there are three unlabeled sets of very good slides of the cells of the common pea plant with one set showing Mitosis, one set showing Meiosis I, and one set showing Meiosis II. To repeat, the slides are unlabeled so the students don’t know which process is occurring in which set. However, the students know that the common pea plant has 14 total chromosomes (or 7 pairs of chromosomes). Explain carefully what Student J would be looking for at the…

Is there interphase again between meiosis I and meiosis II?

Draw a diagram of meiosis in a cell where 2n = 6, in a case where there is interchromosomal mixing. Use a clearly labelled colour code (what does each colour represent?) to represent the chromosomes.
