Selective breeding is the process of breeding plants and animals for a particualar trait.
The advantages of selective breeding is that it can produce fitter, healthier, and stronger andimals. It can also help produce animals that have higher yield of milke, produce more eggs, and have a higher quality of meat. Therefore, it rules out the disabilty of weakness and illness's. Another advantage is that the breeder gets to choose which animal fits their critera and work from there.
However, there are also some disadvantages aswell. Such as getting rid of the variety because the animals would be just like the one it was breeded to be like. In this source of breeding there's never a surprise, the breeder already knows what the animals will look like when they start to breed. Selective breeding can also cause genetic disorders such as imbred depression.
