متن کاملBoris Ephrussi (1901-1979)
Boris Ephrussi studied fruit flies, yeast, and mouse [3] genetics and development while working in France and the US during the twentieth century. In yeast, Ephrussi studied how mutations in the cytoplasm persisted across generations. In mice he studied the genetics of hybrids and the development of cancer. Working with George Wells Beadle [4] on the causes of different eye colors in fruit flie...
