A2 unit 4, topic 3: Inheritance (WJEC A-level Biology)

This bundle of 7 lessons has been designed to cover the following specification points in topic 3 of A2 unit 4 of the WJEC A-level Biology specification:

[a]: alleles as different forms of the same gene
[b]: the principles of monohybrid Mendelian inheritance including simple crosses involving codominance
[c]: the principles of dihybrid Mendelian inheritance including simple crosses involving linkage
[d]: the use of the chi squared test
[e]: sex linkage as illustrated by haemophilia and Duchenne muscular hypertrophy
[f]: gene mutation as illustrated by sickle cell anaemia and chromosome mutations as illustrated by Down syndrome
[h]: Epigenetics as the control of gene expression without changes to the DNA sequence

Each of the lessons is fully-resourced and contains a wide range of tasks that will engage and motivate the students whilst covering the detailed content of this topic. Any exam questions that are found in the resources have markschemes embedded into the PowerPoint
