NEET 2022, Biology Q71: Theories of Evolution
NEET2022Biology
Q.
Natural selection where more individuals acquire specific character value other than the mean character value, leads to:
- A
Stabilising change
- B
Directional change
- C
Disruptive change
- D
Random change
Solution
Three patterns of natural selection are commonly recognised. Stabilising selection favours the average phenotype. Disruptive selection favours both extremes against the mean. Directional selection favours one extreme phenotype over the mean.
When more individuals shift away from the mean toward a specific (one) character value, the population is undergoing directional selection.
