Prize share: 1/1
By conducting statistical studies of the way genetic traits are passed on in fruit flies, Thomas Hunt Morgan broke new ground in genetics during the first decade of the 20th century. His work confirmed that genes are stored in chromosomes inside cell nuclei. He came to understand that genes are organized in a long row inside chromosomes and how traits related to each other correspond to genes that lie close to one another on the chromosomes. He also discovered the "crossover" phenomenon, in which parts of different chromosomes can trade places with one another.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
