2. Aim #45: How does genetic engineering compare and contrast to selective breeding?

3. Selective Breeding/ Artificial Selection

4. 1) What is Breeding?
To produce offspring

5. 2) What is meant by being Selective?
What music do
you like?
The power to choose or
pick out from among others.

6. 3) Can you now define Selective Breeding?
The process of choosing a few organisms
with desirable traits to serve as the parents
of the next generation.

7. Golden Doodle 

8. 4) Types of Selective Breeding:
a) Hybridization/Crossbreeding: is the process of
crossing dissimilar individuals to bring together the
best of both organisms. +

9. Real Example of Hybridization:+ =
Horse
Donkey
Mule
Big, Fast,
Excitable
Small, Slow,
Calm
Strong, Endurance,
Calm
The hybrid is often stronger and hardier than its parents:
Hybrid Vigor

10. Real Example of Hybridization:
Burbank’s hybrid crosses combined
the disease resistance of one plant
with the food-producing capacity
of another.
American horticulturist Luther Burbank ( ) developed a special potato. Burbank, while trying to improve the Irish potato, developed a hybrid that was more disease resistant. He introduced the Burbank potato to Ireland to help combat the blight epidemic.

11. Real Example: Liger
Male Lion
Female Tiger

12. Real Example: Tigon
Male Tiger
Female Lion

13. Types of Selective Breeding
b) Inbreeding: is the continued breeding of organisms
with similar characteristics.
Breeders try to maintain
certain characteristics.

14. Inbreeding: Advantages:
- desirable traits, like resistance to disease or strength of an organism, are collected.
Disadvantages:
-recessive disorders tend to increase.

15. Types of Selective Breeding:
c) Mass Selection: is choosing the best plants and
animals from a large number for further breeding.

16. Selective Breeding ~2 minutes

17. 5) What are some benefits of selective breeding?
Produce crops resistant to
disease.
2) Produce crops that are bigger.
Produce animals that have
less fat.
4) Seedless fruit!!!

18. 6) Genetic Engineering vs. Selective Breeding:
Selective Breeding utilizes
natural reproduction to get
desired characteristics.
Genetic engineering requires
the altering of genes
to get desired characteristics.
