The exchange of DNA between chromosomes during the early formation of sperm and egg cells normally is limited to assure fertility.
But when there are too many of these genetic exchanges, called crossover events, the segregation of chromosomes into eggs is flawed, biologists have learned in a project done across three labs at the University of Oregon and Northwestern University.
