Variation, Sex, and Social Cooperation: Molecular Population Genetics of the Social Amoeba Dictyostelium discoideum
Figure 8
Decay of linkage disequilibrium with distance in chromosome 4.
(A) Pairwise r2 plotted against distance. Linkage disequilibrium is calculated only for the SNPs that have at least 10% frequency in the sample. A permutation analysis indicates that the decay of LD with distance is significant (P<0.031). (B) Plot of mean r2 in various distance bins. The solid horizontal line gives the mean r2 and the dashed line is the 80th percentile for unlinked markers. The baseline linkage disequilibrium in D. discoideum is achieved between ∼10–25 kb.
