Final Summary

This summer went by fast! I feel I have accomplished a lot!

The goal of my project was to determine if genes required for sexual reproduction are undergoing selection to facilitate speciation in the yeast Saccharomyces paradoxus. Saccharomyces paradoxus is woodland yeast found in Europe and North America. In a previous lab, my advisor found evidence of speciation in this yeast. In a recent migration event, a European Saccharomyces paradoxus population migrated to North America. This Migrant population exhibited mating discrimination towards potential North American mates while its ancestral European populations did not. This behavior likely evolved in the Migrant population to avoid reproducing with genetically incompatible North American potential mates, as the offspring of inter-population pairings were substantially less viable. This served as evidence for speciation.
