What is the process of choosing parent organisms for desired characteristics called?

Back

Artificial selection.

What is the difference between natural selection and artificial selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring, while artificial selection is the intentional breeding of organisms for desired traits.
