- BBranching descent and natural selection are the two key concepts of Darwinian Theory of evolution
- CLamarckism is based on inheritance of acquired character
- DThe concept of mutation, gene flow, genetic drift, gene recombination and natural selection affect Hardy-Weinberg equilibrium
Explanation
The Hardy-Weinberg principle states that allele frequencies in a population REMAIN CONSTANT (stable) from generation to generation in the absence of evolutionary influences - it does not say they are unstable. The other options correctly describe Darwinian concepts, Lamarckism and the factors disturbing Hardy-Weinberg equilibrium. The answer is (A).
