What is the relationship between artificial selection and breeding?

According to some sources, the concepts of “Artificial selection” and “Selection” are synonymous. To be more precise, selection is the breeding of new subspecies of organisms by a person, as well as improving the characteristics of existing ones, such as, for example, resistance to low temperatures. Artificial selection is the selection of individuals for crossing by a person. That is, we can say that the method of artificial selection is used in selection. Another method is genetic modification.
