Conservation of habitats (AQA A-level Biology)

AQA A-level Biology Topic 7: Genetics, populations, evolution and ecosystems

This bundle contains 15 fully-resourced and detailed lessons that have been designed to cover the content of topic 7 of the AQA A-level Biology specification which concerns genetics, populations, evolution and ecosystems. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and previous knowledge checks allow them to assess their progress on the current topic as well as challenging them to make links to other related topics. Most of the tasks are differentiated to allow differing abilities to access the work and be challenged. The following sub-topics are covered in this bundle of lessons: * The use of genetic terminology * The inheritance of one or two genes in monohybrid and dihybrid crosses * Codominant and multiple alleles * The inheritance of sex-linked characteristics * Autosomal linkage * Epistasis as a gene interaction * The use of the chi-squared test * Calculating allele frequencies using the Hardy-Weinberg principle * Causes of phenotypic variation * Stabilising, directional and disruptive selection * Genetic drift * Allopatric and sympatric speciation * Species, populations, communities and ecosystems * Factors affecting the populations in ecosystems * Estimating the size of a population using randomly placed quadrats, transects and the mark-release-recapture method * Conservation of habitats frequently involves the management of succession This is one of the 8 topics which have to be covered over the length of the 2 year course and therefore it is expected that the teaching time for this bundle will be in excess of 2 months If you want to see the quality of the lessons before purchasing then the lessons on codominant and multiple alleles, epistasis and phenotypic variation are free resources to download
