About The Cover

Cover image expansion

COVER This cover is a melding of old and new. The fruit flies are 1934 drawings by E. M. Wallace, which have been superimposed on nucleotide sequence information. They are a reminder of the rich history surrounding Drosophila melanogaster genetics and the new avenues to research that are being opened by the announcement and initial analyses of the Drosophila genome sequence in the special section, beginning on page 2181, and related features. [Drawings are courtesy of the Archives, California Institute of Technology]
