Question
Researchers have found that most feral cats in a neighborhood have whiskers measuring about 12 cm. If stabilizing selection acts on this population for 15 generations, what would you expect to see??
- The number of cats with 12 cm long whiskers will keep increasing.
- Most cats will have whiskers less than 12 cm long.
- Most cats will have whiskers more than 12 cm long.
- Most cats will have whiskers either less than or more than 12 cm long, and very few cats will have whiskers of 12 cm.
Hint:
Even more cats with 12 cm long whiskers.
The correct answer is: Most cats will have whiskers more than 12 cm long.
- Selection acts on phenotypic characters regardless of their origin, and it has the ability to keep or delete the characters' genetic base.
- Artificial selection refers to any selective breeding conducted on purpose by humans that results in the evolution of domesticated creatures.
- When the selection is repeated for more generations, the dominant characters rises more.
