P represents the frequency of the dominant allele (in decimal form) of a gene

q represents the frequency of the recessive allele (in decimal form) of a gene

These 2 alleles are different; one is dominant, one is recessive.

p^2 = the frequency of homozygous dominant individuals in the population (decimal form)

2pq = the frequency of heterozygous individuals in the population (decimal form)

q^2 = the frequency of homozygous recessive in the population (decimal form)
