Module 6.1.2: Patterns of inheritance (OCR A-Level Biology A)

Each of the 13 lessons included in this bundle are fully-resourced and have been designed to cover the content as detailed in module 6.1.2 (Patterns of inheritance) of the OCR A-Level Biology A specification. The specification points that are covered within these lessons include:

• The contribution of environmental and genetic factors to phenotypic variation
• How sexual reproduction can lead to genetic variation within a species
• Genetic diagrams to show patterns of inheritance
• The use of phenotypic ratios to identify autosomal and sex linkage and epistasis
• Using the chi-squared test
• The factors that can affect the evolution of a species
• The use of the Hardy-Weinberg principle to calculate allele frequencies
• The role of isolating mechanisms in the evolution of a new species

The lessons have been written to include a wide range of activities and numerous understanding and prior knowledge checks so students can assess their progress against the current topic as well as be challenged to make links to other topics within this module and earlier modules.
