To add or "collect" the best traits from parent species to be included into a new generation of offspring; similar to the process of "natural selection", but speeded up.
For example, if a plant breeder was looking to breed a flower with a long stem over 75cm, what he would do is to go through all the plants in the field or nursery - any of those having a stem shorter than 75cm would be removed (the process is called "roging" as in roge) and not allowed to cross pollinate with those having stems over 75cm.
Genetic probability would ensure that a high percentage of the offspring of these plants would be over 75cm. The next season he would do the same thing and remove all the plants under 75cm; again there would be fewer plants to cross with.
After doing this for a number of generations the genetic trait for all short plants should be almost removed from the parent population.
Of course they normally would do this process for a number of desired traits all at the same time. E.g. over 75cm with red flowers and no thorns.

Selective breeding supports Darwins theory because, we adapt to our environments and believe whoever is compatible with breeding will pass on the trait, even if that means outside their own species.

∙ 13y agoLook at the dog in general and and some of the miniature breeds in particular, all artificially selected in less than a hundred years in some cases. The phenotype, morphology and behavior, sculpted by those with some foal in mind and control of breeding; the environmental analogue. The environment can do this more slowly and blindly over many tears to earth's organisms. It is the same exact physical process; one directed, goal oriented, and progressive. The other, natural selection, has no goals, no direction and is not progressive, but it still has the change over time in populations of organisms.

What technique has been used to modify agricultural plants?
Genetic modification is a new technique. The oldest is domestication, where you select and breed the best plants or animals.
What is pure breeding?
Pure breeding is the process of selectively breeding animals to produce some desired, different, animal.
Why do animals need plants and why do plants need animals?
animals need plants because animals like deer depend on plants like grass(to eat). and plants need animals because if the animals did not eat the plants then the plants would become an invasive species. and then it would be hard to take back, or exterminate the plant.
The food plants make is what?
Photosynthesis

Why do farmers selectively breed animals?
farmers selectivly breed cattle to get the characteristics they desire for the job they are going to put the offspring to do

Selectively breeding plants and animals to accentuate certain characteristics demonstrates what concept?
artificial selection
What is the process by which humans select plants or animals for breeding based on disired traits?
They selectively breed them. So that the animal has the best characteristics possible. Examples are pigs with more fat or sheep with thicker wool.
Samples of biotechnology?
An examples of early biotechnologies includes domesticating plants and animals and then selectively breeding them for specific characteristics .Recent developments in biotechnology include: genetically modified plants and animals, cell therapies, and nanotechnology.
A class of animals or plants that have the same characteristics and are able to breed together?

When humans choose certain animals and plants that have useful features and breed more of these organism?
reproduce
Why would someone cross breed plants and animals?
Because if you cross animals you can end up with a really funky pet. If you cross plants it might make them prettier. But I'm not sure about that one.
How can humans selectively breed a vegetable to produce a more desirable crop?
because they want to
What have been produced by selective breeding?
What *has And many many animals. All our house pets and farm animals are selectively breeded, and also plants. This is done for many reasons, eg to domesticate animals like dogs, to increase quantity and quality of milk production in cows, to ensue a higher yield in plants eg wheat.
