Hybrids between flowering plant species often exhibit reduced fitness, including sterility and
inviability. Such hybrid incompatibilities create barriers to genetic exchange that can …

Mimulus guttatus and M. nasutus are an evolutionary and ecological model sister species
pair differentiated by ecology, mating system, and partial reproductive isolation. Despite …

Much evidence has shown that postzygotic reproductive isolation (hybrid inviability or sterility)
evolves by the accumulation of interlocus incompatibilities between diverging populations. …

Recent molecular investigations of hybrid incompatibilities have revealed fascinating patterns
of genetic interactions that have been interpreted as the remnants of a history of selfish …

… Two alternative explanations are consistent with the observed pattern of polymorphism and
shared genetic variation in Mimulus species: (1) the persistence of polymorphism within M. …

Hybrid incompatibilities play a critical role in the evolution and maintenance of species. We
have discovered a simple genetic incompatibility that causes lethality in hybrids between two …

… genotyped per individual; AM Kenney and AL Sweigart, unpublished data), a pattern observed
in known M. sookensis individuals (Sweigart et al. 2008; Modliszewski & Willis 2012). We …

… Finally, we are concerned about the stability of the current circumscription by Barker & al.
(2012) given that it may not have been sufficiently vetted by peer review. The manuscript was …

Understanding the process by which hybrid incompatibility alleles become established in
natural populations remains a major challenge to evolutionary biology. Previously, we …
