Hardy-Weinberg's Five Assumptions

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Hardy-Weinberg equilibrium assumes an infinite population, no mutation, no migration, random mating, and no selection — conditions no real population fully meets.

Show

A small, migrating, selectively pressured population violates several assumptions at once, exactly what makes it worth comparing against the model.

Watch for

These five assumptions define an idealized baseline — violating them is the norm, not the exception, for any real population.
