The table shows the outcome of two cell divisions, each starting with one diploid cell containing 16 chromosomes.
Table
| Division | Daughter cells produced | Chromosomes per daughter cell | Genetic similarity of daughter cells |
|---|---|---|---|
| P | 2 | 16 | identical |
| Q | 4 | 8 | different |
Which division produces cells suitable for restoring the diploid number at fertilisation?
P, because fusion of two daughter cells restores 16 chromosomes
Q, because fusion of two daughter cells restores 16 chromosomes
Q, because fusion of four daughter cells restores 16 chromosomes
P, because fusion of four daughter cells restores 16 chromosomes
