What are the similarities between selective breeding and genetic engineering?

Genetic engineering is the combining of DNA from different species and can only be done in the laboratory. Traditional plant and animal breeding stay within the species to get the desired result. Some similarities: Both genetic engineering and selective breeding result in modification of an organism's genotype. In other words, the organism's genes are changed in some way. If one or more genes from another species are introduced, the resulting genome consists of recombinant DNA.

In both processes, an out side source is in control, rather than natural selection. (Selective breeding is sometimes referred to as artificial selection.) So humans decide which individual animals or plants to retain in each generation.

And in both processes, the purpose is to make the livestock or crop better from a human point of view.
