Artificial Selection of Dogs

By: Morgan McManus and Deanna D'Amico

What is Artificial selection?

Artificial Selection is the manual breeding of two organisms in which the breeder selects organisms with certain desirable traits.

Steps of Artificial Selection

1. decide which characteristics are important enough to select

2. choose parents that show these characteristics

3. choose the best offspring from parents to produce the next generation

4. repeat the process continuously

How is it being used Currently?

  • It is being used in our everyday pets, farm animals, and food.

  • For pets, breeders create the type of animal that is eye catching to the buyer.
  • It allows for them to make domesticated, hypoallergenic, or a specific sized pets.
Evo-Devo: Dog Breeding


  • It can create new mutations
  • It may further exist harmful mutations
  • There is a risk of new genetic mutations that can appear in the new offspring
  • Artificial breeding is very expensive
  • It is inhumane to be breeding animals for desired traits


  • It can breed harmful traits out
  • Causes a variation of species
  • Allows people to produce desirable traits
  • Physically, it affects what the offspring of the the 2 parents will look like

Problems in the Future

  • Selective breeding has put many purebred dogs at risk such as affecting body and behavior. From this, future generations will have the same genes.
  • It than can make some of the diseases more dangerous as all the organisms would get affected.
  • Overtime, breeding the same dogs with the same genes, the diseases will be spread faster.
  • Instead, naturally breed random dogs, instead of breeding the same dogs to get the same appearances
