Document Summary

Modification of a species by human intervention so that certain desirable traits are represented in successive generations. For example, different breeds of domestic dogs are the result of artificial selection. Diversify food species : nearly all domestic turkeys are of the same white-feathered variety (a), which has been selected for its high production of breast meat and rapid growth in crowded conditions. These turkeys must be arti cially inseminated, hatched in incubators, and raised in protected houses. Bourbon red (b) is an heirloom breed that retains the ability to y, to nd its own food, to mate, and to rear o spring. Artificial selection & crossbreeding (which is selective breeding) versus. Taking a gene from a cell of one species & inserting into another (gmo) Use enzymes to cut gene segments from species a (i. e. , a bacterium) Enzymes to insert genes into species b (i. e. , corn)
