Artificial selection or selective breeding is a process of selecting the “advantageous” characteristics from the plants or animals by humans and using them for breeding. There are many advantages of artificial selection:
• More agricultural products, gaining higher profit (for example more milk from cow, or more fruit)
• Elimination of diseases by identifying the plants/animals with disease
• Production of superior breed.
On the other hand, negative effects might also occur, so the disadvantages of artificial selection are:
• Genetic mutations
• Loss of genes
• Diseases
All of these negative impacts are connected and often arise from the breeding of desirable organisms.
