Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When humans breed organisms with specific traits to influence the traits of the next generation, it is ____
A
Adaptation
B
Natural breeding
C
Natural selection
D
Selective breeding
Explanation: 

Detailed explanation-1: -Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields.

Detailed explanation-2: -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-3: -Selective breeding was established as a scientific practice by Robert Bakewell during the British Agricultural Revolution in the 18th century. Arguably, his most important breeding program was with sheep. Using native stock, he was able to quickly select for large, yet fine-boned sheep, with long, lustrous wool.

Detailed explanation-4: -Description. Selective breeding is when humans choose what animals should breed and when. Natural breeding is when nature chooses what animals breed.

Detailed explanation-5: -Selective breeding is a process in which humans breed specific parents to create offspring with desirable characteristics. Examples include dogs bred for specific work tasks or fruit bred to be sweeter.
