Natural selection where more individuals acquire specific character value other than the mean character value, leads to:
Options
- ADirectional change
- BDisruptive change
- CRandom change
- DStabilising change
Correct answer
A. Directional change
Step-by-step solution
If the organisms/individuals at one extreme of the distribution contribute more offspring to the next generation than other individuals do, then the mean of the population will change. This changes the normal distribution into one tailed-distribution. This is the case of directional selection. If directional selectional operates for many generations, an evolutionary trend within the population results.
