These activities look good, but as a general rule, I avoid having 2 pairs of chromosomes since this number 2 is confusing:
each double helix has 2 strands
each chromosome can consist of 2 sisters
A pair of homologs is 2 chromosomes
If often use an odd number of pairs. This can help illustrate the point that if there are on odd number of chromosomes in a cell, meiosis 1 must have been completed.
