Biology majors Nora Vogel ’11 and Caleb Corliss ’13 discussed their poster titled “Genetic Variation for Invasiveness: Are there Monster Genotypes in Polygonum cespitosum?” They’ve spent the summer trying to understand what role “monster” genotypes (genotypes with the highest relative fitness) play in the invasive spread of this species. Their advisor is Sonia Sultan, chair of the Biology Department, professor of biology, professor of environmental studies.
