because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding
Artificial selection, which is analogous to natural selection. The breeder chooses which characteristics are desirable and breeds towards those characteristics.
natural selection
Artificial selection refers to the process of intentionally breeding desirable traits in either plants or animals. It is also known as selective breeding.
Natural selection is when organisms with a desirable trait mate and produce babies with that trait. The process of elimination will eventually diminish any that do not have that trait/
artificial selection
Because the offspring of an organism with a desirable inherited trait is more likely to survive than the offspring of an organism with a desirable acquired trait (because the offspring of an organism with a desirable acquired trait will not have its parent's desirable trait).
The principle of natural selection is that the fastest or the strongest (in other words the most skill at a trait) would be the most desirable mate and the weak ones that lacked these skills or mutations like thumbs would not be mated with. So the principle of natural selection is we will always find the strongest, fastest or the most intelligent or other advanced traits more desirable.

breeding and selection.
"Choicest" means the best or most desirable selection or option available. It refers to something of the highest quality or excellence.
