Gene duplicates cause hybrid lethality between sympatric species of Mimulus.
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 closely related species of yellow monkeyflower (Mimulus guttatus and M.nasutus).This hybrid incompatibility, which causes one sixteenth Colloidal Silver of F2 hybr
