Specification 3.12, 4.8 · Paper 1
A feature passed genetically from parents to offspring.
Revise: AllelesDifferent offspring can inherit different combinations of the alleles carried by their biological parents. Their genetic instructions—and therefore some of their inherited characteristics—may differ from those of their siblings and parents.
Specification B5.2d, B6.2c · Paper 2 (Foundation), Paper 4 (Higher)
A feature influenced by genetic information that can be passed from parents to offspring.
Revise: Evolution definitionEvolution is a change in the inherited characteristics of a population over time, through natural selection. These changes occur across generations and may eventually result in the formation of new species.
A feature of an organism that can be passed genetically from parents to offspring.

For an explanation question, give the full link: different allele → different DNA information → potentially different protein → different inherited characteristic.
For an ‘explain’ question, link each choice of breeding parents to the inherited characteristics of their offspring, then explain why repeating the selection over generations changes the population.
Define evolution at the population level: write about changes in inherited characteristics over generations, not changes to an individual during its lifetime.
