You do not allow evolution to occur, for you are evolution in selective breeding.
to save the endangered animals
they get really itchy sometimes
it will effect the smoothness of the road
Yes. This has almost been done, in fact, say some. A breeding-back programme has commenced, through selective breeding of the southern Plains Zebras.
Selective breeding
um i really think that selective breeding is really wrong people thinks its funny but its really sad because selective breeding is abusing animals and maybe someone can make a illness and kill people etc. but i think its very wrong
http://www.pedigreedatabase.com/german_shepherd_dog/forum/17623.html The website has some pictures of show dogs that have deformed backs and really short legs (show German Shepherds are supposed to have a curved back). I don't know if it counts because it was technically supposed to happen, but it's still a bit extreme.
A cattle breeder breeds and raises cattle to sell. They can breed the cattle for many different things. Some of these cattle could be for show or some for just beef.
The female two toed sloth is probably one of the most selevtive breeding animals. Her mate must do the can-can before she will breed with him. Of course, the most selevtive in biology it the venemous tentacular.
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.
Genetic Engineering allows scientists to transfer genes from one organism to an organism of a different species; and in Selective Breeding organisms within the same species with certain desirable characteristics are mated to produce a new variety. The difference between the two is in Genetic Engineering manually transfers genes between species and Selective Breeding mates varieties within the same species to produce a new variety.
Many farmers and breeders use selective breeding because they need as good a young as they can get. Breeders often use selective breeding because they want the best looking animal they can get- this involves using the two best of his animals (one male, one female) and breeding them toghether to get an almost guarenteed good outcome. Farmers use selective breeding because they often want the biggest animal they can get- a small cow wont sell for as much as a larger cow. This is why they use selective breeding to get a good outcome, instead of a small animal that wont earn its keep and more :)
