Additional file 8: of Estimation of linkage disequilibrium and effective population size in New Zealand sheep using three different methods to create genetic maps

LD decay over genetic distances and evolution of N e over time estimated using the three methods in CompRCP sheep. The LD curve for the CompRCP breed is similar to those observed for Comprcp2, but present a higher LD at short distances and a relatively high N e after 15 generations. Knowing the breed composition of CompRCP, the results are consistent with what would be expected; i.e. a lower LD at short distances but very persistent, and a greater N e than that observed in pure breeds. The tests of variances show almost no significant differences between methods except for the N e estimation between M1 and M2, and M1 and M3. Test of means show, however, that the differences between each of the three methods are almost always significant for both LD and N e . (TIFF 117Â kb
