Inheritance: dihydrid, autosomal linkage and epistasis

For a really quick explanation about my website and videos spend 2 minutes watching my channel trailer https://www.youtube.com/watch?v=7sfl8_aAWk0

At the start of this video is a quick reminder of the key terms in inheritance and the process of meiosis both of which are essential foundations.
Dihybrid inheritace (aka non-linked genes) and autosomal inheritance are described and explained with examples, the latter being compared to sex-linkage. Epistasis is then described and explained, using an example.
The first 2 topics are covered by all A level exam boards (OCR A&B, AQA, Edexcel B, Eduqas/WJEC) EXCEPT Edexcel A it seems; as well as CIE.
Although epistasis is not required as a term by all exam boards, it could well be included as an application (problem solving) question by any of them - only AQA and OCR A seems to specify it in the syllabus.
