Research recently published by Jesse Hollister, U of T Post-doctoral fellow, along with his supervisors, Professor Marc Johnson and Professor Stephen Wright demonstrate accumulation of mutations with transition to asexual reproduction. Hollister is now an assistant professor at Stony Brook University in New York.
