Answer
This statement is incorrect. In image 9, the chromatids are still attached at their centromeres. Chromatids separate during anaphase II, which occurs later in the meiotic process.
Step 2
Cells after the stage shown in image 10 are haploid.

Answer
This statement is correct. By the end of meiosis I, the cells are halved to the haploid number, which is established after telophase I.
Step 3

Answer
This statement is incorrect. DNA replication occurs during the S phase of the cell cycle, prior to entering meiosis, not during the stages shown in the meiosis images.
