Ответ:
Your question is in three parts, you asked for a help on the THIRD part, it is provided below.
The combinations of chromosomes present in
A) daughter cells following mitosis will be C1/C2 , M1/M2 , S1/S2
B) the first meiotic metaphase will be C1/C2 , M1/M2 , S1/S2
C) haploid cells following both divisions of meiosis will be C1, M1, S1 & C2, M2, S2
Explanation:
A diploid cell has two sets of chromosomes called homologous chromosomes and represented as 2n.
For part A: The daughter cells after mitosis has SAME chromosome number and content as parent diploid cell C1/C2 , M1/M2 , S1/S2 as homologues because NO exchange of material (crossing over) occur during mitotic division
For part B: During the 1st meiotic metaphase, chromosomes of the diploid cell are just assembled, they are YET to be separated, thus its chromosome is SIMILAR to diploid cell
For part C: haploid cells following both divisions of meiosis will be C1, M1, S1 & C2, M2, S2. This is because during meiosis, the number of chromosomes in diploid cell is HALVED (2n becomes n). Thus, haploid cells carries ONLY one set of chromosomes in diploid cell.
