DNA is the genetic code which makes up genes, which are responsible for giving an organism a specific characteristic.

Some variation is passed on via genes and some variation is the result of differences in the surroundings, or what an individual does.

Collecting data on the differences between members of a species can give two different types of results: continuous and discontinuous.

Characteristics like eye colour and genetic diseases are inherited.

Evolution explains how better adapted organisms have an advantage.

Natural selection is known as ‘the survival of the fittest’. The best adapted organisms are able to survive.

Evolution is the process by which small changes in organisms occur over long periods of time and new species are formed.

Selective breeding is when organisms are deliberately bred so their offspring have the desirable characteristics.

Genetic conditions are passed from parents to their children. Learn about conditions that are inherited, such as sickle cell disorder and cystic fibrosis.
