LineEventProbability
(i)No recombination eventpLSpSR
(ii)An SR-recombination event makes the allele at the R-locus escape the sweep without the allele at the L-locus.pLS(1 − pSR)
(iii)An LS-recombination event makes the allele at the L-locus escape the sweep without the allele at the R-locus.(1 – pLS)pSR
(iv)An LS-recombination event followed by an SR-recombination event brings the alleles at the L- and the R-locus into the wild-type background.ℙ[(iv) or (v)] = (1 – pLS)(1 – pSR)
(v)Same as (iv) but in reverse order of the LS- and SR-recombination events.
