Research Description:
Bret Payseur uses genetics and genomics to understand mechanisms of evolution. Payseur and his students are discovering how one species becomes two, how organisms adapt to new environments, and how meiotic recombination evolves – all from a genetic perspective. Payseur’s research focuses on natural variation in a powerful genetic model organism, the house mouse.
