Frequency Tm Tm

/t -n ((1 ~ fi)2qdl - qdwlttot) frequency(Tm,r) = -=-, (12.53)

where the mean fitness in habitat /, Wv is given by the sum of the numerators of (12.53). (iii) Gamete production then occurs. The frequency of the mutant allele in each habitat after gamete production is q;G;, (12.54a)

where

(iv) Finally, after dispersal, a fraction p, of the gamete pool of habitat / is made up of immigrant gametes. Therefore, we have qc{t + 1)\ = (Gc{ 1 - Pc) GbPc \(qc(t)\ qb(t+l)J V GcPb Gb{l - Pb))\qb{t)J- K ' '

We are now ready to conduct a local stability analysis of model (12.55) for the equilibrium qc = qb = 0. Doing so, and supposing that there is no inbreeding in the central habitat (fc = 0), gives the local stability matrix
