please for the love of fuck someone help me with this. what am i supposed to be getting form this equation? im probably retarded but i feel like the equation is redundant. im getting the same things out of it, as im putting into it.

You can use it to see the frequency of individual alleles in a population given the ratios of phenotypes, and you can find the ratio of phenotypes given the frequency of alleles in a population.
I'll give you an example after I've finished using the bathroom

Imagine you have a population with two alleles of a gene, T and t.
If the frequency of T in the population is 0.7, what proportion of individuals are heterozygous for this gene?
p = 0.7, q = 0.3, so the frequency of people heterozygous would be 2 * 0.7 * 0.3 = 0.42.
If a population is 90% homozygous for T, what are the allele frequencies in the population?
p^2 = 0.9, so p = 0.949.
