Topics 4.4 - 4.7 (AQA A-level Biology)

These 9 lessons are highly detailed and are filled with a wide range of tasks that will engage the students whilst covering the following specification points in topics 4.4, 4.5, 4.6 and 4.7 of the AQA A-level Biology specification:

4.4
Genetic diversity as the number of different alleles of genes in a population and a factor enabling natural selection to occur
The principles of natural selection in the evolution of populations
Directional and stabilising selection
Natural selection results in anatomical, physiological or behavioural adaptations

4.5
Two organisms belong to the same species if they are able to produce fertile offspring
The taxonomic hierarchy comprising domain, kingdom, phylum, class, order, family, genus and species
The use of the binomial name to identify species

4.6
Biodiversity can relate to a range of habitats
Species richness
Calculating an index of diversity
The balance between conservation and farming

4.7
Investigating genetic diversity with, or between species, by comparing observable characteristics or nucleic acids and the structure of proteins
Calculating and interpreting the mean and standard deviation
