a group of organisms that can reproduce to produce fertile offspring

differences between members of the same species

the external space around an organism that influences it

the choices an individual makes as to how they live their life

related to the genetic material (DNA) and genes that an individual has

Variation within species

Science

Reproduction and variation

Continuous and discontinuous variation: practical

Discontinuous variation: data handling and analysis

Continuous variation: data handling and analysis

Pupils will learn that variation between individuals of the same species means some individuals are better adapted to compete, which can lead to natural selection and cause the heritable characteristics of a species to change (evolve) over generations.

Pupils learned that organisms can be identified and classified into hierarchical groups based upon similarities and differences in their characteristics at the macroscopic and cellular levels.

This unit examines variation within species, both continuous and discontinuous, using measurements and graphical representations. It also emphasises objectivity, accuracy, precision, and repeatability in investigations, the use of appropriate techniques, and the effective presentation of data.

Variation (differences within species)

Subjects which particular individuals may be sensitive to, eg, adoption, migration, bereavement or death, divorce, poverty, deprivation.
