Cambridge Biology for the IB Diploma Scheme of work for Chapter 10, Genetics II Syllabus section Content Time required Outline of lessons Coursebook resources Worksheets Teacher’s resources / Teaching ideas 10.1 Meiosis 2 lessons Review the description of the behaviour of chromosomes in the phases of meiosis and outline the formation of chiasmata in crossing over p236–240 Support: Q1 Short-answer Qs p239 Extension: Q2 Practical activity: modelling meiosis using modelling clay or similar Explain how meiosis results in genetic variety through crossing over in prophase I and random orientation in metaphase I; explain the relationship between Mendel’s law of independent assortment and meiosis 10.2 Dihybrid crosses and gene linkage 3 lessons End-ofchapter Qs p251–252: Q5 Link to TOK: Mendel’s work in a historical context Link to ICT: check Mendel’s statistics Calculate and predict genotypes and phenotypes of offspring in dihybrid crosses involving unlinked autosomal genes, and distinguish between autosomes and sex chromosomes p240–248 Explain how crossing over between non-sister chromatids at prophase I can result in exchange of alleles End-ofchapter Qs p251–252: Q1, Q2, Q3, Q4, Q6, Q7 Worked examples p241–248 Support: Q3, Q4 Extension: Q1, Q3, Q4 Short-answer Qs p241, p248 Practice theoretical questions in Coursebook and Worksheets Exemplar exam question Explain linkage and an example of a cross between two linked genes; identify offspring that are recombinants in a dihybrid cross involving linked genes 10.3 Polygenic inheritance 1 lesson Explain how polygenic inheritance contributes to continuous variation using the example of human skin colour and one other example p248–250 TOK p250 Support: Q2 Link to ICT: examples of polygenes Note: 1 lesson = approximately 40 minutes Copyright Cambridge University Press 2011.
