Question

tell if each example is natural selection, artificial selection or genetic engineering

1. viruses changed in a lab to create vaccines
2. turkeys have lost the ability to fly due to breeding of larger birds
3. frogs with longer tongues can catch bugs farther away
4. trees with shorter branches collect less snow and dont break
5. bright colored flowers attract more pollinators
6. a drought resistant gene is inserted into wheat
7. squirrels that can store acorns are more likely to survive winter
8. female birds prefer to mate with bright colored males
9. a dna strand was inserted into corn to produce larger ears of corn
10. horses are bred to run faster
11. eagles with larger wings use less energy to fly farther & find food
12. growers prefer red roses
13. fish living on the bottom are less likely to get caught by birds
14. bacteria become resistant to medicines
15. scientists remove traits that make chicken sensitive to disease
16. farmers breed cows to produce more milk
17. more brown snakes are caught during summer
18. dogs are bred for their ability to hunt rabbits
19. a corn gene was added to sunflowers to produce more seeds
20. deer with large antlers are able to chase away other males

Explanation:

Natural selection: Traits improve survival/reproduction in wild, no human direction.
Artificial selection: Humans breed organisms for desired traits.
Genetic engineering: Directly modifying an organism's DNA in a lab.

5. Natural Selection
6. Artificial Selection
7. Natural Selection
8. Natural Selection
9. Genetic Engineering
10. Artificial Selection
11. (This is not a selection/engineering example; it is a seasonal observation, but if categorized by the framework, it does not fit any. However, if forced to align with the options, it is none, but following the task's categories: No applicable selection/engineering type)
