You are studying a hair color locus in a population of 1000 bears. There are two alleles at this locus, H (frequency p=0.5) and h (frequency q=0.5). If the population is at HWE with respect to locus H, how many bears are heterozygous at locus H?
A. 250
B. The answer depends on whether other loci are also at HWE
C. 500
