Disadvantages of selective breeding?
If it is an animal, it would be unfair to the animal, it could cause genetic problems and the animal could get sick easier. If it's a plant, it could cause environmental problems if it uses more water than other plants around it, causing the plants around it to dry out and birds to lose homes and insects to lose food. It all depends on what it is.

Selective breeding is the process in which two animals from the same species reproduce due to useful characteristics. Two animals with a certain type of characteristic are… bred together to produce offspring. Then the offspring with the most useful characteristic breeds with another offspring to produce more offspring. This process continues for generations until the offspring consistently have the useful characteristic farmers or scientists are looking for. Cross-breeding is a type of selective breeding except with animals from two organisms from the same species but not the same breed. Selective breeding is one of the most common causes for a wide range of breeds in animals and varieties in plants. this is incorrect It is the process which humans use animal breeding and plant breeding to selectively develop particular characteristics by choosing which typically animal or plant males and females will sexually reproduce and have offspring together
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.
advantages: we get more breeds and more animals/plants easier people can make more more Disadvantages the animals/plants can have genetic diseases It is har…d to get rid of the genetic diseases because you have to breed them out
The advantages of selective breeding include producing a dog that meets the standard of the breed. Disadvantages include producing dogs with very short faces, squat legs, …and large bodies.
With selective breeding the gene pool becomes less diverse.
Selective breeding is known as artificial selection because you are selecting the mates instead of letting them select their own. It's bypassing nature so it's classified …as artificial. Outside persuasion that directly effects the outcome of the natural selection.
Selective breeding is when a species is purposely breed to have certain characteristics. Ex. lots of dogs are breed to have a shiny coat, of a certain color of fur etc. Natura…l selection is having nature choose your characteristics. Ex. On the Galapagos islands, the finches have different depths of beaks. All they eat are seeds. The beaks ranges from 6 to 14 mm deep when the rainfall is normal. During years of drought, the seeds they eat have less water and the seeds are large and tough to crack open. Then, the finches with small beaks won't be able to crack the seeds open because they have weaker beaks than finches with larger beaks. The small beak finches die of starvation and the large beak finches live to pass on their genes of having large beaks. Over time, the finches with small beaks all die off and there will only be finches with larger beaks. This is natural selection.
Could create genetic mutation that harm the animal but may create ones that make it adaptable into living and reproducing.
all breeds of animal can be selective breed DaveScriv added: Indeed all breeds of domestic livestock were created by selective breeding, although it looks more obvious on some… than others. Taking a few chicken breeds as examples, Drentse & Friesians (both from The Netherlands) don't look much different from wild Jungle Fowl in size & shape (although bred in many plumage colour varieties, most of which are different from JF colours), so don't look as though they've been subjected to much selective breeding, but they've still been selectively bred to an extent, and have existed for over 1000 years (long before they were 'officially recognised breeds') in their home regions to be active little birds which could find most of their own food (their original peasant owners couldn't spare much valuable grain in this mainly cattle/pasture region) and be nimble and alert enough to avoid being eaten by foxes. The Netherlands is also one home country of Sabelpoot Bantams (also developed in England as 'Booted Bantams' & Germany as 'Federfussige Zwerghuhner', one of the most extreme (huge feathering on legs & feet, plus an wide range of plumage colours & patterns) and obvious examples of selective breeding. Some of the colour varieties are fairly new, but Booteds/Federfussiges/Sabelpoots generally were first developed well over 200 years ago. Google the breed names to get pictures.
its when you take a desirable trait to produce a certain kind of offspring. like making bigger sweeter strawberries or making horses faster.
Selective breeding in domesticated animals is the process of a breeder developing a cultivated breed over time, and selecting qualities within individuals of the breed that wi…ll be best to pass on to the next generation.
Selective breeding is when farmers or bioligists breed certain animals together because of their traits. This is man made. For example, cattle are breeded together based on po…sitive traits. Natural Selection, however, is natural obviously. Here the concept of "the survival of the fittest" is put into place. Animals that run the fastest, have the longest necks, etc. tend to survive. Then, when these animals breed, their characteristics are passed on from generation to generation and become more common.

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.
Breeding is just breeding any pair of parents together to get offspring, whereas selected breeding is choosing a certain set of parents and targeting a few specific traits you… want the offspring to have, such as fur length, coloration, or body shape.
To get fish the color you want.

well some times they come out with deformities not bad ones but there are some risks the advantages is that they come out looking better than ever
why do we make selectively breed happen
