Cells from an animal species were examined during cell division. A student predicted that each daughter cell would have twice as many chromosomes as the original cell.
| Cell examined | Number of chromosomes |
|---|---|
| Original cell, after DNA copying | 18 |
| Daughter cell 1 | 18 |
| Daughter cell 2 | 18 |
Explain how the data show whether the student’s prediction is correct, and how each daughter cell gets its chromosome number.
