Reproductive barriers are often assumed to arise from fixed genetic differences between species, despite frequent individual variation in the strength of reproductive isolation between populations. Larson et al. report polymorphism at several hybrid male sterility loci in house mice, and their results demonstrate that selection against deleterious hybrid interactions can drive the introgression of hybrid incompatibilities, highlighting the need for more extensive sampling of natural variation in speciation studies.
