Detailed explanation-1: -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-2: -Selective Cross Breeding Pollen with the genes for a desired trait is transferred from plants of one crop variety to the flowers of another variety with other desirable traits. Eventually, through careful selection of offspring, the desired trait will appear in a new variety of plants.
Detailed explanation-3: -The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.
Detailed explanation-4: -The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated.
