WebYes Hardy-Weinberg is mainly used to calculate the expected frequency assuming: no mutations, no gene transfer, random mating, large population, and no selection. However if we know the actual frequency of the homozygotes (i.e. p^2 and q^2) in the actual population we can compare to an expected value.
