Contrast one major difference between selective breeding and genetic engineering

Selective breeding is where humans choose individual of the same species that have a trait that favors economic growth or any other benefits, then breeding these favorable species until most of the population are the species with the favorable genes. Meanwhile, genetic engineering is where human alters, changes, inserts DNA to modify organisms.

Therefore, one major difference is that selective breeding does not include altering the DNA, while genetic engineering is the altering of DNA.
