Figure 4. The number of zerofold degenerate mutations fixed in the 25 kb regions flanking the S-locus increases with dominance of the S-allele associated.

Each dot represents the value obtained for haplotypes linked to one S-allele in one population. The correlations evaluated by a generalised linear model (GLM) are represented by lines, with confidence intervals represented in grey. The dominance was considered as a continuous variable. (A) A. halleri. Black dots correspond to the Nivelle population, grey dots to the Mortagne population. (B) A. lyrata. Red dots correspond to the IND population, black dots to the PIN population, and blue dots to the TSS population.
