Similarities Between

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.
