Forward genetics definition

WebForward mutation changes the A allele to the a allele at a rate (u); backward mutation changes a to A at a rate (v). We can express the frequency (p) of the A allele in the next generation (p t+1) in terms of these opposing forward and reverse mutations, much like forward and reverse chemical equations: (p t+1) = p t (1-u) + q t (v).
