Results: The effective population size derived from squared correlation coefficients between SNP alleles (r2) was 69. The maximum value of r2 ... (ROH) was calculated for seven length categories of ROHs, and ranged from 0. ... We showed that the minimal density setting (in kb/SNP) can strongly affect the outcome of the ROH analysis. This is most relevant for medium density SNP arrays since in PLINK the default density setting is roughly equal to the average density for most livestock and pet species (50 kb/SNP). This is clearly visible … See more The effect of LD pruning on ROH analysis is highly population dependent (Fig. 1 and Additional file 2: Figure S1).
