Answer:
Explanation:) In mitosis, two genetically identical daughter cells are produced. Thus, the only possible combination of chromosomes is C1/C2/M1/M2/S1/S2 since all genetic material is inherited. b) The first meiotic division serves to split homologous pairs into two different cells, which are now haploid. There are 8 possible combinations of chromosomes (2 chromosomes for each homologous pair). For instance, a cell at this stage could inherit C1/M1/S1, or C2/M1/S1, or C1/M2/S1, etc. c) The same 8 combinations as above. The second meiotic division splits double-stranded chromosomes of each of these haploid cells into two daughter cells each so that only single-stranded chromosomes remain. Since no crossing over...
