Fig. 3: Observed and expected patterns in haplotype diversity and linkage disequilibrium at eight Z-linked loci in Bicyclus anynana.

a Distributions of the proportional change between 1993 and 2006 (~70 generations) in haplotype diversity (Hd) at corresponding loci shown on a simplified chromosome b. Bootstrap distribution of the observed data (gold); simulated distribution with overdominance at C5197 (green); neutral expectation (dotted line). c Entropy-based linkage disequilibrium (eLD) among all pairs of loci. Values in the upper-half matrix are for the Leiden population in 1993, and in the lower-half matrix for the descendant Liverpool population in 2006. In parentheses, the mean and standard deviation of eLD in a sample of 100 simulations assuming overdominance at C5197. Colour gradient is proportional to the magnitude of eLD.
