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 identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Detailed explanation-3: -How does selective breeding work? Farmers select parents with desirable characteristics and breed them together. From their offspring, they again choose those with the best combination of traits and breed them together. The process is repeated over many generations .
Detailed explanation-4: -When a farmer breeds only his or her best livestock, the process involved is? Artificial selection.
Detailed explanation-5: -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.
