This fully-resourced lesson challenges the students to use fully labelled genetic diagrams to interpret the results of monohybrid and dihybrid crosses as detailed in topic 7.1 (Inheritance) of the AQA A-level Biology specification. Step-by-step guides are used to demonstrate how diagrams for the inheritance of one and two genes should be constructed and a focus is given to the areas where students commonly make mistakes, such as in writing out the gametes. The main task of each section of the lesson provides an opportunity for the students to apply their understanding by calculating phenotypic ratios. All of the questions have fully-explained mark schemes and students can assess their progress and address any misconceptions immediately. Key genetic terminology is used throughout the lesson and mirrors that used in actual exam questions.

AQA A-level Biology Topic 7: Genetics, populations, evolution and ecosystems
This bundle contains 17 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 * Species exist as one or more populations * The concepts of gene pool and allele frequency * 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 * Primary succession, from colonisation by pioneer species to climax community * 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

Topic 7.1: Inheritance (AQA A-level Biology)
This bundle contains 7 lessons which combine to cover the content of topic 7.1 (Inheritance) of the AQA A-level Biology specification. All 7 are fully-resourced and contain differentiated tasks which allow students of differing abilities to access the work whilst being challenged. They have been designed to include a wide range of activities that check the understanding of the current topic as well as making links between other parts of this topics and topics covered earlier in the course. The lessons on codominant and multiple alleles and epistasis are free so you can sample the quality of this bundle before deciding to make a purchase
