disadvantage: selective breeding gets rid of variety
advantage: selective breeding rules out weakness and disability
disadvantage: isn't that what Hitler tried to do with humans in WWII? do we really want to be like him?
Selective breeding(or artificial selection) produces traits which may be advantagious to us, but be a disadvantage to the animal.Here are some examples-The lapps of northern Europe herd and breed the wild deer, selecting docile animals. The resulting herds could not survive in the wild.Cows with big udders are good for us , but are probably painful for the cow. English bulldogs mght be considered a cool looking dog, but have breathing difficulties and such small pelvises that they often have to give birth by causation.
Advantages: Can produce fitter, stronger animals or animals of a higher yield of milk, meat or eggs for example. Can produce animals better suited to survive in poor climates or marginal conditions, thus preserving human food supplies and saving life. Can ensure the eradication of hereditary sickness in some blood lines.
Disadvantages: For show animals such wild kitten eatingas some dogs, it is practised quite strictly by breeders aiming at a certain look which is set down as the breed "standard"- many Dalmation puppies are euthanased because they do not exhibit the breed standards for example, so there are serious moral questions to it too.Too much close interbreeding to obtain certain cosmetic traits can also result in the amplifying of inherent illnesses - like the bulldogs mentioned above, or German shephered dogs with hip problems and so on - in fact, these issues are rapidly worsening in recent years with dogs in particular. keep in mind it will eat your babies if you anger them.
I don't breed animals myself but I have researched this topic. Selective breeding is used to obtain desired traits in the offspring. This technique has been practised on domestic animals, but mostly livestock. One advantage of this technique is that you can create pets to fit your lifestyle. I know that people who are allergic to dog hair order poodle crosses because they don't molt, but a family can still have another breed of dog. In livestock it is used to fatten up cows, or keep the racing gene in horses. This is also how the bloodlines horses stay "purebred".
Selective breeding is important to farmers and animal breeders because they want to reproduce or "select" a certain kind of trait.
For example: if a certain trait in a cow made better tasting milk, the farmer would then want that same result because it sold better or at a higher price.
OR
If an animal breeder, oh lets say a dog breeder, saw a very unique coat in a pup and it became very popular to have but rare to get; that animal breeder would want to reproduce that trait. And so the dog would be bred with another similar dog to make the gene stronger.
By selective breeding, one can choose two mates of an organism with the more dominant and/or successful genes in order to create a "more perfect" organism of that species. Using selective breeding correctly, you can eliminate bad/recessive/mutative genes from future generations of an organism whether it be to better its survival or its looks. In example, some more hairy gogs like terriors are prone to eye problems. Through successful and professional selective breeding, that particualr health problem can be eliminated in future generations of the breed.
One of the benefits of selective breeding is being able to increase favorable characteristics. Another benefit is lessening the chance of defects.
reduction of health care and educational expenses
For animals - To get a purebred that will sell for more
For Humans - To keep money, royalties and assets in the family
Selective breeding is done in cattle because cattlemen and breeders with their cattle herds and/or breeds they care for and manage are always improving the genetics and productivity of their animals. Every breed has its faults, so cattlemen and farmers are always selecting animals to improve the cowherd and culling out those that are not improving the herd.
Selective breeding and artificial selection.
One of the most important things farmers did that improved the quality of their livestock, according to Charles Darwin, was to participate in selective breeding. This brought out the best features of each type of livestock, while ridding the offspring of unwanted characteristics.
Some farmers may refer to them as Brood Cows.
Yes. That's all a bull is worth, really.
Farmers use selective breeding all the time.
Farmers
By using selective breeding the farmers can get bedder produce out of the offspring of the animals.
Selective breeding is a way of maintaining animal existence. Selective breeding is when the strong survive. If only the weak survived then all animals would die out quickly

False
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 :)
Selective breeding
This is called selective breeding or artificial selection, opposed to natural selection.
It is called selective breeding.
Selective breeding and artificial selection.
Farmers learned to be careful in choosing the plants and animals used for breeding. The breeding of plants or animals with desirable traits in order to produce more offspring with those traits is called selective breeding. Using selective breeding results in better crops.Some of the crops resists pests and diseases.Other crops are bigger,stay fresh longer, or taste better.
