Figure 5. Inferred placement of all detected isolation loci acting on (A) pollen fertility, and (B) seed fertility, between SL and each of SH and SP.

Details and effect size data for each locus are in Table S3. Loci that are unique to one species pair must be due to mutations that occurred on a branch that is unique to that species pair. Placement of the shared isolation mutations on branch b is based on the inference that they are derived in the common ancestor of SH/SP (see main text, Figures 2 and 3, Text S2, and Figure S3).
