Q

Process (Artificial Selection)

A
  • The method
  • The desired characteristics are identified
  • They are bred together
  • Only the offspring exhibiting the desired characteristics are bred
  • This is repeated over several generations until the desired trait is fully developed

Q

CONTRASTING Natural Selection vs Artificial Selection

A

NATURAL SELECTION
* Organisms better adapted to their environment tend to survive and produce more offspring.
* Natural process.
* Maintains variation within populations.
* Slow process.
* Advantageous traits are inherited over time.

ARTIFICIAL SELECTION
* The breeder selects organisms to produce desirable traits in successive generations.
* Humanmade process.
* Can decrease diversity.
* Rapid process due to human intervention.
* Desirable traits are inherited over time

Q

Benefits (of Artifical Selection)

A
  • Humans are in charge!
  • Enables the development of specific traits for various purposes.
  • Accelerates desirable traits in a shorter time frame.

Q

Negatives (of Artifical Selection)

A
  • Alters natural evolution, which may impact an organism’s ability to survive in the natural world
  • Often involves inbreeding, reducing genetic diversity.
  • Ethical concerns when it comes to the “well-being” of an organism
