Study System Mimulus allotetraploids derived from M. guttatus and M. nasutus. Nuclear loci and cpDNA variation indicate multiple origins.
Evolutionary genetics of polyploids
* Does parallel genetic evolution occur in naturally-occuring, independently-derived polyploid populations?
* Can polyploidy lead to novel heritable genetic variation in ecologically important traits?
* What evolutionary forces act on novel genetic variation (if existing) in neotetraploids?
