 * __10.1 Meiosis __**

10.1.1 Describe the behaviour of the chromosomes in the phases of meiosis. 10.1.2 Outline the formation of chiasmata in the process of crossing over. 10.1.3 Explain how meiosis results in an effectively infinite genetic variety in gametes through crossing over in prophase I and random orientation in metaphase I. 10.1.4 State Mendel’s law of independent assortment. 10.1.5 Explain the relationship between Mendel’s law of independent assortment and meiosis.


 * __10.2 Dihybrid crosses and gene linkage __**

10.2.1 Calculate and predict the genotypic and phenotypic ratio of offspring of dihybrid crosses involving unlinked autosomal genes 10.2.2 Distinguish between //autosomes //and //sex chromosomes //. 10.2.3 Explain how crossing over between non-sister chromatids of a homologous pair in prophase I can result in an exchange of alleles. 10.2.4 Define //linkage group //<span style="font-family: "MyriadPro-Regular","sans-serif"; font-size: 12px;">. <span style="font-family: "MyriadPro-Regular","sans-serif"; font-size: 12.66px;">10.2.5 Explain an example of a cross between two linked genes. <span style="font-family: "MyriadPro-Regular","sans-serif"; font-size: 12.66px;">10.2.6 Identify which of the offspring are recombinants in a dihybrid cross involving linked genes.

<span style="font-family: "MyriadPro-Regular","sans-serif"; font-size: 12px;">10.3.1 Define //<span style="font-family: "MyriadPro-It","sans-serif"; font-size: 12px;">polygenic inheritance //<span style="font-family: "MyriadPro-Regular","sans-serif"; font-size: 12px;">. <span style="font-family: "MyriadPro-Regular","sans-serif"; font-size: 12px;">10.3.2 Explain that polygenic inheritance can contribute to continuous variation using two examples, one of which must be human skin colour.
