The **Hardy-Weinberg principle** describes:
AThe conservation of allele/genotype frequencies in an idealised population with no evolutionary force
BHow natural selection drives evolution
CHow mutations arise
DGenetic drift in small populations
Answer & Solution
Correct answer: A. The conservation of allele/genotype frequencies in an idealised population with no evolutionary force
Hardy-Weinberg: in a large, randomly mating, diploid population with no selection, mutation, migration or drift, allele frequencies (p, q) and genotype frequencies ($p^2$, $2pq$, $q^2$) remain constant generation to generation. Deviations indicate evolutionary forces at work.
