Advantages of selective breeding?
An advantage of selective breeding is that producers can produce cows or bulls with characteristics that improve the breed or the herd itself, or produce more income for the producer when calves are sold. Selective breeding means herd improvement, on things such as milking ability, mothering ability, carcass quality, forage utilization efficiency, calving ease, stayability, birth weights, weaning weights, etc.

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.
In both processes the favourable characteristics are passes on to the next generation.Both processes eventually form a new species.
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 is when parents with idealistic traits are crossed (mate) to produce offspring with exaggerated versions of these traits. Multiple matings usually occur to …create a line with 100% abundance of the idealistic trait.
The two types of selective breeding are Inbreeding and Hybridization.
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 b…red 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.
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.
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.
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.
Step One : Breed those individuals your plant/animal to have Step Two : Choose the characteristic you want Step Three : Select individuals that have the characteristic S…tep Four : Wait until they have offspring Step Five : Choose the offspring that have the characteristic you want Step Six : Repeat the process all over again (probably several times) By Hollie-Leigh Scott 9s :) XD Steps of selective breeding:Using Genes,DNA and Chromosones 1.Humans take the sperm from the male animal. 2.They then separate the gene from the DNA. 3.They then take the egg from the female and join the two together. 4.Using micro injection they inject the gene into the female egg. 5.After the egg is fertilized they inject it into the female animal. 6.If the offspring produced have the desirable traits then they repeat the process. If not then they start all over again using a different method. Johann Labuschagne

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
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

Selective breeding helps to rule out weakness and disability in animals and helps make farming more lucrative for farmers by providing more robust animals for sale. Corn woul…d only have ten kernels or less per ear withour selective breeding!
