The coalescent is an accumulation of waiting times. We can think of it as standard queuing process where the times are exponentially distributed with rate k(k − 1)/(2 × 2N) [for most elaboration in this chapter I use the Wright-Fisher model as a guide, for the Moran model the rate would be k(k−1)/(2× (2N)2) ]. The coalescent makes no assumptions about the interaction of the intervals, we will a...
We extend the spatial -Fleming–Viot process introduced in [Electron. J. Probab. 15 (2010) 162–216] to incorporate recombination. The process models allele frequencies in a population which is distributed over the twodimensional torus T(L) of sidelength L and is subject to two kinds of reproduction events: small events of radius O(1) and much rarer large events of radius O(Lα) for some α ∈ (0,1]...
