Hardy-Weinberg's Five Assumptions
Captions available
The idea
Hardy-Weinberg equilibrium assumes an infinite population, no mutation, no migration, random mating, and no selection — conditions no real population fully meets.
In practice
A small, migrating, selectively pressured population violates several assumptions at once, exactly what makes it worth comparing against the model.
Where people slip
These five assumptions define an idealized baseline — violating them is the norm, not the exception, for any real population.
