Selective breeding happens within closely related species. useful Techniques
GM Food produces a wide range of characteristics that aren't possible with selective breeding. It can alter an organism's DNA with much greater precision-genes can also be transfered or manipulated
When you modify genetic material directly, rather than going through natural breeding, you
* have more direct control over what to change
* can mix genes from species that it wouldn't be possible to breed naturally
As an example, the GloFish (see related link) is a fluorescent small fish sold for aquariums. The fluorescence was created by taking a zebra fish and adding genetic material from jellyfish and coral. This would not be possible with selective breeding, as you can't mate a coral and a fish.
Genetic modification opens a whole new range of possibilities. Along with the associated risks.
Artificial selection is controlled totally from the outside and the selector is usually man. Men want certain attributes in organisms they domesticate and these attributes would not necessarily contribute to the organisms survival and reproduction if the organism was not protected by the artificial selector, man.
selective breeding and genetic resistance
selective breeding; been going on for thousands of years. genetic engineering; been going on for decades.
In natural selection, the animals take time and evolve slowly. In selective breeding, humans can transfer genes from one organism into another organism.
selective breeding not inbreeding
Selective breeding.
You do not allow evolution to occur, for you are evolution in selective breeding.
Selective Breeding of course!
By selective breeding.
Selective breeding is used for more rapid evolution or artificial breeding.
Evolution following selective breeding.
evolution
Selective breeding.
Natural Selection is different from Selective Breeding beacuse the environment controls the traits the animal or plant gets. Selective Breeding is the traits desired are the ones bred
Artificial selection, also called selective breeding, is a form of human intervention in plant or animal evolution.
