Question

20 POINTS!!! PLS ANSWER!!!

Interpret: Directional selection occurs when individuals at one end of a range are more likely to survive than intermediate individuals or individuals at the opposite end of the range. Stabilizing selection occurs when intermediate individuals are the most likely to survive.

Is directional selection, stabilizing selection, or both operating in this example? Explain.

Answer 1

I believe both directional and stabilizing selection are operating in this example since only the large-beaked finches were able to survive the drought while the smallest-beaked finches disappeared. But also, we need to highlight after the second year stabilizing selection occurred because finches with large beak depth were the most likely to survive than those with smaller beaks, that is why that specific type of beak became more common.

Step-by-step explanation:

Answer 2

Answers:

Stabilizing selection occurs when intermediate individuals are the most likely to survive.

Step-by-step explanation:

Both because for example the birds with larger beaks could survive the drought and after 2 years stabilizing selection also occurs.

Answers:

Directional selection occurs when individuals with traits on one side of mean in their population survive or reproduce more than those on the other.
