Evolution
A change in the inherited characteristics of a population over time through the process of natural selection
2 of 14
Natural selection
A process which gives rise to phenotypes best suited to their environment
3 of 14
Selective breeding
The process by which humans breed plants and animals for particular genetic characteristics
4 of 14
Genetic engineering
A process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired characteristic

(BIO ONLY) Cuttings
Simple method used to produce many identical new plants from a parent plant
