Which genetic principle states that allele frequencies remain constant in a population under ideal conditions?

The Hardy-Weinberg Principle states that allele frequencies remain constant unless affected by evolutionary forces. This follows from NCERT principle where relation explains outcome clearly for students.

Which factor violates Hardy-Weinberg equilibrium?

Hardy-Weinberg equilibrium provides null model where allele and genotype frequencies remain constant across generations in absence of evolution, given by p2+2pq+q2=1. Assumptions include large random-mating population, no selection, mutation, migration or drift. Deviations indicate evolutionary forces at work. It allows estimating carrier frequencies for recessive diseases and testing if population is evolving. Therefore principle states Directional selection remains stable under idealized conditions. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET,
