Inheritance, variation and evolution

Reproduction occurs in all organisms. DNA is important, as it allows new proteins to be synthesised. Mutations in the DNA can have serious implications.

This interactive quiz is suitable for GCSE Biology (single science) students studying the genome, genes and DNA.

Our genes are inherited from our parents, and the different combinations of these genes make us unique. Genetic inheritance controls the characteristics of all living things.

This interactive quiz is suitable for GCSE Biology (single science) students studying genes and inheritance and how the latter controls the characteristics of living things.

This interactive quiz is suitable for GCSE Biology (single science) students studying inherited diseases and genetic testing.

Variation in species can be generated by genetics. Mutations arise spontaneously and can sometimes lead to genetic disorders or death. Genes can be inserted into a genome through genetic engineering.

This interactive quiz is suitable for GCSE Biology (single science) students studying variation and selective breeding n different species.

Evolution is the change of inherited characteristics within a population over time through natural selection, which may result in the formation of a new species.

This interactive quiz is suitable for GCSE Biology (single science) students studying evolution and the concept of survival of the fittest.

Living things are classified using a system developed by Carl Linnaeus. Organisms are commonly named by the binomial system of genus and species.

This interactive quiz is suitable for GCSE Biology (single science) students studying how organisms have been classified into systems.

Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
