AQA GCSE Biology B6 Inheritance, Variation and Evolution: 17 lessons ready to teach, with a topic test

You get all 17 lessons for this unit, planned and ready to teach in editable PowerPoint and matched to the AQA 8461 specification.

The presentations come as two zip files, Part 1 and Part 2.

What your classes work through

• Sexual and asexual reproduction and meiosis: Pupils predict the chromosome number in a dog gamete from a table.
• Comparing sexual and asexual reproduction: Pupils explain why sexual reproduction helps a species survive environmental change.
• DNA and the genome: Pupils explain how a gene leads to a protein and to eye colour.
• The structure of DNA: Pupils evaluate a claim that four DNA bases code for only four proteins.
• Genetic inheritance and genetic crosses: Pupils compare offspring ratios from two mouse crosses and explain the difference.
• Inherited disorders and sex determination: Pupils predict the chance of a child inheriting polydactyly from a Dd parent.
• Variation and mutation: Pupils evaluate whether constant mutation means every species changes rapidly.
• Evolution by natural selection: Pupils pick the natural selection explanation for grey lizards on grey rocks.
• Selective breeding: Pupils read a milk yield graph and find the mean increase per generation.
• Genetic engineering: Pupils give reasons why bacteria with the human insulin gene make useful insulin.
• Cloning: Pupils describe cloning a rare orchid by tissue culture and explain why clones match.
• Darwin and the theory of evolution: Pupils use natural selection to explain thicker rabbit fur in a colder climate.
• Wallace and speciation: Pupils judge whether two snail groups split by a lake are separate species.
• The story of genetics and the evidence for evolution: Pupils explain why Mendel’s work was only accepted in the early 1900s.
• Fossils and extinction: Pupils match three ways fossils form to the correct description of each.
• Antibiotic resistant bacteria: Pupils predict the 2022 resistance figure and justify it with natural selection.
• Classification of living organisms: Pupils describe the three-domain system and explain why classification changed.

Who it is for
