WebLet u = rate of forward mutation = 0.86 * 10-3, and let v= rate of back-mutation = 0.47 * 10-3. Let p be the frequency of A and q be the frequency of a. We know that at equilibrium p = v/(u+v), and q = 1-p. So q = 1- [0.47 * 10-3/(0.86* 10-3 + 0.47 * 10-3)] = 0.65. WebFeb 26, 2024 · Summary – Forward vs Reverse Genetics.
