Hybrid Sterility and Segregation Distortion in Drosophila pseudoobscura and Drosophila persimilis
Speciation has occurred countless times throughout history, and yet the genetic mechanisms that lead to speciation are still missing pieces. Here, we describe the genetics of two processes that can act alone or together ...
The Role of Polyploidy in Phenotypic and Genomic Evolution in the Shy Monkeyflower, <i>Mimulus sookensis<i>
In an ever-changing world, evolution is an essential process that may allow organisms to adapt to their environment through natural selection. All evolutionary processes act through a single fundamental medium: genetic variation. ...
Evolution on Arbitrary Fitness Landscapes when Mutation is Weak
Evolutionary dynamics can be notoriously complex and difficult to analyze. In this dissertation I describe a population genetic regime where the dynamics are simple enough to allow a relatively complete and elegant treatment. ...
