Use the chromosome bead models to model meiosis with one, two, or three pairs of homologous chromosomes. By doing this exercise you should be able to determine all the different combinations of chromosomes that are possible in gametes due to the independent assortment of homologous pairs. Diagram all possible arrangements in the circles provided using red for maternal chromosomes and yellow
for paternal chromosomes.
You will disregard crossing over between homologous chromosomes for this exercise.
A cell with one pair of homologous chromosomes (n = 1)
Assemble two duplicated chromosomes, one red and one yellow, with 10 beads on each end of the centromere. By modeling meiosis, determine all possible combinations of chromosomes in gametes when n = 1 assuming there is no crossing over, and diagram each combination in the circles below using different colors for maternal and paternal chromosomes.
