What are the 4 examples of artificial selection?

Artificial Selection Examples

  • Farming Livestock. Aggressive male stock has been castrated for centuries, while those males with genotypes, phenotypes (dominant traits) of use to humans have been used as breeding stock.
  • Dogs. Artificial selection has been used for millennia.
  • Wheat.
  • Pest Control.
  • Fainting Goats.

What is artificial selection example?

Dog breeding is another prime example of artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding. Artificial selection appeals to humans since it is faster than natural selection and allows humans to mold organisms to their needs.

What is an example of artificial selection in animals?

A common example of artificial selection in animals is dog breeding. As with racehorses, particular traits are desirable in different breeds of dogs that compete in dog shows. The judges look at coat coloring and patterns, behavior, and even teeth.
