Selective breeding is done to increase the likely hood of certain traits desirable by the breeder. If a dog breeder liked the shape of a dog's ears, she would mate that dog with another dog with similar shaped ears. Incestuous mating occurs quite frequently in animal breeding due to the increased genetic similarity. All dogs belong to the same species, and therefor can produce viable offspring. The reason a Chihuahua and a German Shepard are so different is because of the ancient practice of selective animal breeding.

Selective breeding (or artificial selection) is used in breeding of animals and plants to remove unwanted characteristics. Orchids can be bread via this process in an attempt to control the colour, scent, pattern etc.

In animals selective breeding can be used in much the same fashion.

I strongly suggest reading Richard Dawkins: The greatest show on earth. He explains natural selection and artificial selection brilliantly. He is one of the worlds foremost leading evolutionary biologists.

If a breeder wants a certain trait to be passed on, they will select at least one of the organism that carries this trait. That way, there will at least be a chance that the organism will pass on the trait. After a while, by only breeding animals with the traits desired, the traits will become "permanent"

For example, say a horse breeder only wanted fast horses. If he/she only breeds fast horses with other fast horses, more fast horses will be produced seeing as the "slow gene" is obviously not present in the two parent horses. it is used to produce the best type of whatever. like one corn produces with less corn on it and one corn would have more corn on it, you would select the corn with more to reproduce and make more crop.

Selective breeding is used to bring out certain traits in offspring. Dogs are a good example of this. Some varieties of plants are bred this way as well to bring out good qualities, like cross pollination.

Selective breeding is used because people figured it out when they made the doctor pepper plant in 1256 AD divided by Pi because the soup man with a fat anus likes breeding with 12-year old girls

the pollen from another plant is pushed through the tube in another flower and then a bag is put over the top to stop any more pollen from falling in and fertilising the egg cells
