Topic 8.2: Transfer of genetic information (Edexcel A-level Biology B)

Each of the 6 specification points in topic 8.2 of the Edexcel A-level Biology B specification are covered by the 6 lessons included in this bundle:

(i) Understanding of the key genetic terms
(ii) Be able to construct genetic crosses and pedigree diagrams
(iii) Understand the inheritance of two non-interacting unlinked genes
(iv) Understand that autosomal linkage results from the presence of alleles on the same chromosome
(v) Understand sex linkage on the X chromosome
(vi) Be able to use the chi squared test

The lessons contain step by step guides that walk students through the key details of this topic, such as the construction of genetic crosses or the calculation of the chi squared value. There are also lots of exam-style questions to challenge the students to apply their understanding and the mark schemes that are embedded in the PowerPoints will allow them to assess their progress.
