Hardy Weinberg Principle

Real World Example

Imagine trying to keep a room at a comfortable temperature without any changes in the weather or the thermostat settings. Just as the room remains at a steady temperature when no external factors interfere, the Hardy-Weinberg principle states that allele frequencies in a population stay constant unless a factor like mutation, selection, or migration causes change. In this analogy, the room's temperature represents the allele frequencies, while external factors like weather changes or thermostat adjustments are akin to evolutionary forces that can disrupt genetic equilibrium.
