**A PowerPoint presentation which covers AQA A Level Biology 3.7.1 - Inheritance. ** This PowerPoint includes: A brief overview of Mendel’s investigations and laws. A recap on monohydrid inheritance. Co-dominance. Multiple alleles. Sex-linkage. Dihybrid inheritance. Autosomal linkage Epistasis Over 60 neatly presented PowerPoint slides designed to be delivered in a lecture-style. There are worked examples throughout, but you will need to supplement this with your own worksheets and exam-style questions. If you are confident with this topic area, this should be ** ‘grab & go’** and allow you to deliver the material with ease. As previously mentioned, you will need to supplement this with your own worksheets and exam-style questions.

This is a PowerPoint presentation which covers the following areas as part of AQA A Level Biology 3.7.4 Populations in Ecosystems: Populations of different species form a community. A community and the non-living components of its environment together form an ecosystem. Ecosystems can range in size from the very small to the very large. Within a habitat, a species occupies a niche governed by adaptation to both abiotic and biotic conditions. An ecosystem supports a certain size of population of a species, called the carrying capacity. This population size can vary as a result of: • the effect of abiotic factors • interactions between organisms: interspecific and intraspecific competition and predation.

This resource contains information relevant to older specifications and can be adapted accordingly based on your cohort of students
