Artificial Selection Also called selective breeding

What is artificial selection? Humans choosing traits desirable to them rather than nature choosing traits that are passed on Humans have an effect on the evolution of a species rather than letting nature choose the path of evolution

When is artificial selection used? Domesticated animals such as dogs Farming crops and animals Pharmaceuticals (new drugs) Genetic engineering

Pros and Cons Pros: – Humans can manipulate organisms to benefit them – New variations of organisms can be produced (example: cabbage, broccoli, cauliflower are all variations of the same plant) Cons: – Selectively bred organisms are more susceptible to environmental changes and diseases – Inbreeding can become a problem – In animals artificial selection can cause health problems
