Research Summary:
Dr. Levin's research is currently focused on the function and dynamics of the breeding system in annual species of Phlox. This entails analyses of gene flow via pollen within and among populations, documentation of the number and frequency of self-incompatibility genes within populations, the nature of pollen-pistil incompatibility, the level of competition among pollen tubes in open-pollinated pistils, and the response of populations to selection for greater levels of self-compatibility. His lab is also concerned with documenting the fitness liability of white-flowered variants through demographic studies of white- and red-flowered plants in natural Phlox habitats.
