Natural selection where more individuals acquire specific character value other than the mean character value, leads to :
Directional Change
Disruptive change
Random change
Stabilising change
- If in Natural selection, individuals do not acquire mean value, it can be Disruptive/Directional.
- Hence question is about a specific value other than the mean, hence it has to be Directional
- In Disruptive, peripheral values are selected (at both ends) and this is nonspecific.
Hence, Option (1) is correct.
