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.
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.
Mass selection in animal breeding is when certain animals are chosen for certain desirable traits to pass on. Once those animals are obtained, they are bred to control wha…t traits the offspring have and to create varying lines.
The two types of selective breeding are Inbreeding and Hybridization.
Selective breeding has been existed from approximately 1300-1600. The exact date is not possitive. It started with grain, getting better products' of grain and of coarse… getting more production. However this was an accident, a farmer in Western Europe thought that if he picked the bigger seed's, that bigger crops of grain would appear. At first he wasnt correct, but year's after year's the production of his grain steadily increased, then the secret spilled out to a traveling merchant heading to Germany; and there he suggested to do this and that with the local farmers in a town in Germany.

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.
For some breeds such as Arabians, its to keep their pure bloodlines. Other times it will be because the person breeding may be looking for certain characteristics in conformat…ion or a certain color.
Selective breeding has produced hundreds of different breeds of dog over several centuries. If it wasn't for selective breeding (choosing two dogs with the most desireable fea…tures to breed) then dogs would not have been domesticated. Selective breeding is when a person selects two dogs with the desired features to breed to pass this feature on to their puppies. For example: people who live in a cold climate would want dogs with thick coats, so they would select the dogs with the thickest coats to breed from. However, due to excessive inbreeding, many breeds have now got over-exaggerated features such as greatly shortened legs or domed skulls. This is a downside to selective breeding, when man abuses his control over nature.
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 there are many reasons to why it is expensive but I only know one, and that is that the animals that you have selectively bred may have consequences to the genes it has i…nherited. For example, in a cow, there may be a gene that produces more milk and so people breed cows of those specific genes. However, there may be a gene that is inherited WITH this feature, like mastitis(inflammation of the udder) which means that there would be a lot of money spent on treating every cow of this illness who has the feature of producing more milk.

depending the trait you find most desirable on the animal. like if i want the charcoal color of a Siamese cat's ears, then i would breed the cat, and whatever kitten has that …trait, get the kitten, then breed it again
