Detailed explanation-1: -Selective breeding versus natural selection Natural selection is driven by environmental factors that limit survival and reproduction, such as harsh environments or competition for mates. Selective breeding is also known as artificial selection. Artificial selection is driven by human intervention.

Detailed explanation-2: -Selective breeding is the process by which humans control the breeding of organisms in order to exhibit or eliminate a particular characteristic. Selective breeding uses artificial selection to direct the genetic transfer of desirable traits.

Detailed explanation-3: -Traditional breeding: Modification of plants and animals through selective breeding. Practices used in traditional plant breeding may include aspects of biotechnology such as tissue culture and mutational breeding. Transgene: A gene from one organism inserted into another organism by recombinant DNA techniques.

Detailed explanation-4: -The difference is that traditional forms of breeding change the plant’s genetics indirectly by selecting plants with specific traits, while genetic engineering changes the traits by making changes directly to the DNA. In traditional breeding, crosses are made in a relatively uncontrolled manner.
