The lessons in order
| Ref | Lesson pack | Structure | Worksheet | Quiz | Lab tab |
|---|---|---|---|---|---|
| 16.1 | Meiosis and genetic variation Every gamete you made carries just one chromosome from each of your 23 pairs, and no two gametes carry quite the same set. | Think-Pair-Share | 6 Q, 19 marks | 8 MCQ | tab 1, tab 2 |
| 16.2 | Monohybrid and dihybrid crosses A genetic diagram is a prediction machine: write the parents' genotypes, list every type of gamete, combine them in a Punnett square and read off the ratio. | Mix-Pair-Share | 6 Q, 20 marks | 8 MCQ | tab 3 |
| 16.2 | The chi-squared test Real crosses never give perfect ratios. | Numbered Heads Together | 6 Q, 17 marks | 8 MCQ | tab 4 |
| 16.2 | Genes, proteins and phenotype Albinism, sickle cell anaemia, haemophilia and Huntington's disease look nothing alike, but each follows the same chain: a change in the base sequence of one gene changes a protein, and the faulty protein changes the phenotype. | Corners | 6 Q, 20 marks | 8 MCQ | tab 5 |
| 16.3 | Gene control A bacterium does not waste energy making enzymes for a sugar that is not there, and a pea seedling does not grow until gibberellin tells it to. | Frayer Model | 6 Q, 19 marks | 8 MCQ | tab 6, tab 7 |
Each pack holds the plan, worksheet and quiz for its lesson. Teach the rows in order; the lab tabs match the student lessons.
