Relative fitness relationship at equilibrium.

Post by ghostphish » Fri Oct 31, 2008 10:50 pm

I'm working on this problem for my population genetics class, and I just can't seem to get it. The problem is:

In a basic one locus – 2 allele selection model, assume the following fitness set in which the
allele A is completely dominant with respect to allele a. What is the relationship between the
relative fitnesses (w1 and w2) at equilibrium?

genotype AA Aa aa
relative fitness w1 w1 w2

Now I know that with complete dominance W1>W2, and W1=W12 and the phenotype frequencies are 3:1 for A:a. But I'm not quite sure what they are asking for. Any help would be great.
