Multilocus identity by descent in population genetics: models and predictions

<p>Please find the pseudo dataset (in "data.tgz") of the evolution of Identity-by-descent in a Wright-Fisher population model, with drift as the only evolutionary pressure, with a constant population size, and panmictic without selfing. The individuals are diploids and the initial population are unrelated and non inbred, meaning that chromosome in the initial population are pairwisely different.</p> <p>In "data.tgz", one could find stored all the IBD blocks at specific generations (1,000,000 replicates, over 500 generations, population size of 20 diploid individuals). For each file, the first column is the number of the replicate, the second the number of the individual in the replicate and the third the length of the IBD block. Each line is an IBD block.</p> <p>This dataset was generated with the joint program "ibd-static", with the command line "./ibd -i 20 -r 1000000 -g $g -sa", where$g is the number of generations ranging from 1 to 500.</p> <p>The output file could be summarised in several mean values, what is done by "mfile.R", and the resulting file is "xmean".</p
