What is the process in which humans breed organisms for certain traits?
A
natural selection
B
inheritance
C
artificial selection
D
descent without modification
Explanation: 

Detailed explanation-1: -Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.

Detailed explanation-2: -Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next. People have been artificially selecting plants and animals for thousands of years.

Detailed explanation-3: -Artificial selection, also called “selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.

Detailed explanation-4: -Methods of selection discussed include (1) individual selection (also called mass selection), (2) family selection, (3) sib selection, (4) progeny testing, (5) within-family selection, (6) pedigree selection, and (7) combined selection.

Detailed explanation-5: -Selective breeding versus natural selection Selective breeding is also known as artificial selection. Artificial selection is driven by human intervention.
