Meiosis produces genetically unique daughter cells. The process of meiosis involves two nuclear divisions and forms four haploid daughter cells. Independent segregation and crossing over result in genetically different daughter 0.6 weeks Explain the different outcome of mitosis and meiosis. Explain how meiosis results in variation. Complete diagrams showing the chromosome content of after the first and second meiotic division, when given the chromosome content of the parent cell. Recognise where meiosis occurs when given information about an unfamiliar life cycle. Explain how random fertilisation of haploid gametes further increases genetic variation within a species. Learning activities: introduce the convention of 2n and n. Students then calculate the number of possible chromosome combinations (without crossing over) pair, share: there is more variation possible than our calculated number – where does the extra variation come from? teacher explanation of the process of meiosis, supported by animations and videos students compare and contrast mitosis and meiosis students interpret information about unfamiliar life cycles to identify where meiosis and mitosis are occurring. Skills developed by learning activities: MS 0.5 – use the expression 2n to calculate the possible number of different combinations of chromosomes Specimen assessment material: A-level Paper 1 (set 1) – Q10; AS Paper 1 (set 1) – Q3. Past exam material: BIOL2 June 2013 – Q1; BIOL2 June 2010 – Q5. Rich question: Compare and contrast the similarities and differences between mitosis and meiosis.
