Q
Artificial selection or “Selective Breeding”
A
- Breeding of species to enhance desirable traits.
- Human-directed process done through controlled mating
2
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.
5
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
