Solution
The correct option is C b - directional, c - disruption, a - stabilisation
Natural selection is a process in which organisms which are better adapted to the environment survive and produce more offspring.
Types of natural selection are as follows:
- Stabilising selection
- Directional selection
- Disruptive selection
Stabilisation can occur due to natural selection during which more individuals acquire mean character value and in the graph the peak gets higher for a particular trait.
Directional selection can be seen when more individuals acquire values other than the mean character value and the peak shifts in one direction due to this.
Disruptive selection can be seen when more individuals acquire peripheral character value at both ends of the distribution curve and due to which two peaks are formed.
Hence the correct option is
b. b - directional, c - disruption, a - stabilisation
