Hardy Weinberg Equilibrium

So when given a Hardy Weinberg equilibrium problem, if you are told 14 out of 100 members of a population EXHIBIT or EXPRESS a recessive trait:

then q^2 = 0.14
and you can find q, p, 2pq, whatever the question asks for.

How else could a problem be worded (for example, how would they word a problem to indicate "q" instead of expressed q^2?)

they could say the 14 are "homozygous for the the recessive allele"

They would say the frequency of the allele in the gene pool is q. From this value, you usually can deduce the number of homozygotes for q (q^2), homozygotes for p (p^2) and heterozygotes (2pq).
