New Edexcel IGCSE 9-1 4BI1 syllabus for 2017 first examined in 2019

This is a PowerPoint presentation for the topic - Section 3b Inheritance - Variation and Mutation

3.33 understand that variation within a species can be genetic, environmental, or a combination of both
3.34 understand that mutation is a rare, random change in genetic material that can be inherited
3.35B understand how a change in DNA can affect the phenotype by altering the sequence of amino acids in a protein
3.36B understand how most genetic mutations have no effect on the phenotype, some have a small effect and rarely do they have a significant effect
3.37B understand that the incidence of mutations can be increased by exposure to ionising radiation (for example, gamma rays, x-rays and ultraviolet rays) and some chemical mutagens (for example, chemicals in tobacco)

The file is fully editable, has plenty of original diagrams and animations along with true false concept check questions at the end of the presentation and an exam style question.
