Which genotype does pq represent in the hardy-weinberg equation?
a.) one that has a dominant allel and a recessive allele
b.) one that has two dominant alleles
c.) one that has two recessive alleles
d.) one that has a dominant allele and a neutral allele

The correct answer is A.) one that has a dominant allele and a recessive allele

Hardy-Weinberg principle states that allele frequency in a population is stable and remain constant from generation to generation.

The gene pool remains constant and known as genetic equilibrium.  

                   p² + 2pq + q² = 1  

In the given equation pq represents frequency of heterozygous genotype , that is one dominant allele and one recessive allele.

Over several generations if the gene frequencies remains constant which indicate no evolution has taken place. Change in gene frequencies would indicate that evolution is in progress.
