Bad points of selective breeding?
The main bad thing about selective breeding is that it can be very bad for the animals health. Take the pedigree dog, the King Charles Spaniel. This dog has been selectively bred to have a smaller head so now their brains are two big for their skull. This is very painful for the animal and in the worst cases, the dog has to be put down.

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
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.
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.
In selective breeding the traits that the offspring inheirits is controlled by the person who is doing the breeding. For example if a chihuahua breeder is looking to make smal…ler dogs, they are gonna breed two small dogs with the hope that the puppies will inheirit their parents traits. Natural selection on the other hand is not controlled by humans. It is when offspring inheirit traits that make it more likely to survive. Organisms with certain traits are more likely to survive and reproduce. If there are some mice born, some in the litter are white and the others are brown. When these mice go to find food, the white mice are more easily seen by the keen eyes of an owl than the brown ones. Therefore the brown ones are more likely to reach reproductive age and producing mice. This continues in a cycle until the mice end up almost all being brown.
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.
In general ... the people who do the selecting have no idea what the consequences of their meddling will be. This form of short-sightedness often results in detrimental result…s. It reduces the amount of variation in a species and many activist groups say that we don't have the right in playing God in choosing the direction of a species' development. Also, too close interbreeding to get desired traits means as well as lowering variation, there is an increased risk of passing on genetic diseases to offspring.
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.
dont know your suppossed to give me the answer!!
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.
In Animal Life
Generally it's good, but you have to be a little careful not to breed in undesirable traits along with the ones you want.
it is good as it help farmer to get more money out of it but it can bring serous disease
To get fish the color you want.
In a very limited way: natural selection and selective breeding are almost exactly alike, except that in the case of selective breeding (artificial selection) humans are i…nvolved in selecting which individuals get to raise offspring.
why do we make selectively breed happen
