This resource is a lesson with activities covering the inheritance of epistatic gene content of the A Level Biology specification. This resource includes:

A PowerPoint to lead students through the lesson which includes several genetic crosses which help students to appreciate both dominant and recessive epistatic crosses. The use of phenotypic ratios to identify epistasis and explanations of epistatic crosses.
The lesson assumes students already have an understanding of monogenic inheritance and dihybrid inheritance.

A worksheet containing a range of examination questions which test the students’ understanding of epistasis.
The PowerPoint also has the answers to the student question sheet.
