10.1 - Meiosis
Assessment statements
| DCS Topic Code | Statement | Guidance |
| 10.1.U1 | Chromosomes replicate in interphase before meiosis. | |
| 10.1.U2 | Crossing over is the exchange of DNA material between non-sister homologous chromatids. | |
| 10.1.U3 | Crossing over produces new combinations of alleles on the chromosomes of the haploid cells. | |
| 10.1.U4 | Chiasmata formation between non-sister chromatids can result in an exchange of alleles. | |
| 10.1.U5 | Homologous chromosomes separate in meiosis I. | |
| 10.1.U6 | Sister chromatids separate in meiosis II. | |
| 10.1.U7 | Independent assortment of genes is due to the random orientation of pairs of homologous chromosomes in meiosis I. | |
| 10.1.S1 | Drawing diagrams to show chiasmata formed by crossing over. | Diagrams of chiasmata should show sister chromatids still closely aligned, except at the point where crossing over occurred and a chiasma was formed. |
