selective breeding; biotechnology
Explanation:
Selective breeding is a type of artificial selection that consists of crossing plants/animals with desirable and heritable phenotypic traits in order to increase the frequency of such traits in progeny. Selective breeding can be considered as one of the first biotechnological techniques applied by humans. In the past, the selective breeding technique has allowed obtaining domesticated animals (e.g., dogs from wild wolves) and domesticated crops from their wild ancestors (e.g., maize from its wild ancestor teosinte).
