Tishkoff and Joseph Lachance have found that a bias toward particular types of DNA sequences during gene conversion may be a significant factor in the persistence of heritable diseases in populations around the world.
Tishkoff, a Penn Integrates Knowledge Professor, is the David and Lyn Silfen University Professor in the departments of biology in Penn Arts and Sciences and genetics in the Perelman School of Medicine.
