Explanation:
The fruit fly has 8 chromosomes (2n) in each cell. During interphase of Mitosis, the number of chromosomes at G1 phase is 8.
During the S phase of interphase, DNA replication occurs. This means that each chromosome is duplicated, resulting in two identical sister chromatids held together by a centromere.
Therefore, after the S phase, the number of chromosomes remains the same, but the number of chromatids doubles. In other words, there are still 8 chromosomes, but now there are 16 chromatids (2 chromatids per chromosome).
Summary:
- The fruit fly has 8 chromosomes (2n) in each cell.
- During interphase of Mitosis, the number of chromosomes at G1 phase is 8.
- During the S phase, DNA replication occurs and each chromosome is duplicated.
- After the S phase, the number of chromosomes remains the same (8), but the number of chromatids doubles (16).
- Therefore, the correct answer is option 'A' - 8 chromosomes.
