Chapter 18 AQA A-level Biology. Avoid lost marks in A-Level Biology speciation, natural selection and genetic drift exam questions by knowing the common errors and misconceptions. Increase marks with models and scaffolds for explanations. Learn how to identify when and how to calculate allele frequency using Hardy-Weinberg equations. Many students know the content but fail to turn knowledge into marks due to terminology errors or inability to apply the knowledge to new scenarios. This video helps you avoid losing these marks, helps improve your application of knowledge and subsequently improve grades. #disruptiveselection #stabilisingselection #Hardyweinberg #speciation 0:00 Introduction 0:28 Keeping terminology A-level 0:56 Hardy-weinberg 2:04 Identifying when assumptions not met 2:58 Modelling hardy-Weinberg 7:47 Calculating allele frequency without Hardy-Weinberg 9:00 Explaining natural selection - common errors 11:11 Writing scaffold for natural selection and model answers 15:34 Disruptive, Directional and stabilising selection 18:46 Speciation writing scaffold 21:23 Genetic drift: Bottle neck, Founder effect Subscribe for more lessons, exam tips and A-level Biology support throughout your studies.
