Underdominance Problem 6
Incorrect!
Tutorial to help us answer problem 6.
We are given that q0 = 0.9, which implies that p0 = 0.1. We must now determine if p0 lies to the left or right of 
to decide what happens to p as t → ∞. Using the fitness array 1.8: 1 : 1.2, which is in the form 1 + s1 : 1 : 1 + s2, we find s1 = 0.8 and s2 = 0.2. Using these values of s1 and s2 we find that peq as,
Therefore, because p0 = 0.1 < 0.2 = peq, we know (p, q) → (peq, qeq) = (0, 1) as t → ∞. Thus, p → 0 as t → ∞.
