Explanation
Meiosis is a process of cell division that reduces the chromosome number by half, producing four haploid cells (cells with half the number of chromosomes as the parent cell). In this scenario, each of the four cells formed after meiosis has a chromosome number of 8 and a DNA content of X pg.
The cell cycle consists of interphase and the mitotic phase. Interphase is further divided into three phases: G1, S, and G2. During the G1 phase, the cell grows and prepares for DNA replication. During the S phase, DNA replication occurs. Finally, during the G2 phase, the cell prepares for mitosis by synthesizing proteins and organelles.
At the end of meiosis, the cells have already gone through the S phase of the cell cycle, so they have replicated their DNA. Therefore, at the beginning of the G2 phase, each of the four cells will have a chromosome number of 8 and a DNA content of 2X pg (double the amount of DNA content compared to before DNA replication).
During the mitotic phase, the cells will divide again, resulting in the formation of eight haploid cells, each with a chromosome number of 8 and a DNA content of X pg. Therefore, the correct answer is option D: 16,4X.
