Yes probely is but just try
Genetic drift is the variation of population allele frequency, natural selection changes allele frequency by favoring those alleles that give an organism a reproductive fitness advantage
P + q = 1 <span>correctly represents the possible frequencies of each genotype.
</span>The sum of the allele frequencies at the locus must be equals to 1<span>,
so </span>p<span> + </span>q<span> = </span><span>1</span>
