Infertile animals are not able to have offspring of their own - so are not of any direct value in breeding. Infertile animals may be introduced into populations as a means of population control - for pest species. Sterile males may also be used to see if females are receptive for mating purposes before the intended male mate is transported. An example of this is in the horse breeding industry - where they wish to know whether to bring the stallion in to service the mare. However, a fertile pony, who is unable to breed with the mare - but technically fertile - is usually used.
breeding is when to animals mate and reproduce more of that species of animals
No. Animals will continue to breed as long as there is other animals of their species to breed to. However, no animal can ever be "over-bred."
No. The drones (male bees) are ejected from the colony at the end of the breeding season by the worker bees (infertile females).
Animals in the wild breeding, such as squirrels, rabbits, deer, elephants, etc., are not selective breeding (artificial selection).

Cross breeding is simply taking two breeds of animals and mating them together (Such as a Charolais crossed with a Hereford). Where selective breeding is selecting the what two animals you want bred together to produce a better animal.
By breeding.
cross breeding is taking two different breeds of animals, inbreeding takes the same breed of animals
