IGCSE Biology 9-1 - 3b Inheritance - Genetics

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

This is a PowerPoint presentation for the topic - Section 3b Inheritance - Genetics

3.19 understand how genes exist in alternative forms called alleles which give rise to differences in inherited characteristics
3.20 understand the meaning of the terms: dominant, recessive, homozygous, heterozygous, phenotype, and genotype
3.21B understand the meaning of the term codominance
3.22 understand that most phenotypic features are the result of polygenic inheritance rather than single genes
3.23 describe patterns of monohybrid inheritance using a genetic diagram
3.24 understand how to interpret family pedigrees
3.25 predict probabilities of outcomes from monohybrid crosses
3.26 understand how the sex of a person is controlled by one pair of chromosomes, XX in a female and XY in a male
3.27 describe the determination of the sex of offspring at fertilisation, using a genetic diagram

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.
