Question

in the hardy weinberg equation what does p2 stand for?

Answer 1

If N and n are two homologous alleles in a population:
p = the frequency of the dominant allele, N, in the population
q = the frequency of the recessive allele, n, in the population
p↑2 = frequency of the homozygous dominant genotype, NN, in the population
q↑2 = frequency of the homozygous recessive genotype, nn, in the population
2pq = frequency of the heterozygous genotype. Nn, in the population
