Scientists are discovering that we contain genetic multitudes. Not long ago, researchers had thought it was rare for the cells in a single healthy person to differ genetically in a significant way. But scientists are finding that it’s quite common for an individual to have multiple genomes. A study by Eugen Dhimolea, HMS research fellow in medicine at Dana-Farber Cancer Institute, is cited. Christopher Walsh, the Bullard Professor of Pediatrics and Neurology at Boston Children’s Hospital, who recently published a related review, is also quoted.
