PATHOLOGY

Detailed explanation-1: -If the cells have 12 chromosomes during interphase, the number of chromosomes will be retained as 12 in each of the daughter cells even after the completion of mitosis.

Detailed explanation-2: -Overall, meiosis results in the formation of four haploid cells from a diploid parent cell. So if a cell has 12 chromosomes at the end of meiosis I which is reduction division, it means that the parent cell would have had 24 chromosomes in prophase I.

Detailed explanation-3: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II.

Detailed explanation-4: -In the G1 phase, there are 12 chromosomes. In the S-phase of the cell cycle, the amount of DNA gets doubled. There is doubling of the chromatids but the chromosomes number remains same. The number of chromosomes in the G2 phase will be same as 12 chromosomes and the number of chromatids will be 24.

Detailed explanation-5: -A plant cell has 12 chromosomes at the end of mitosis.
