The relations between the three major Drosophila melanogaster chromosomes and individual differences in geotaxis are assayed in populations selected for positive and negative geotaxis and in an unselected foundation population. The major changes which occur with selection and the differential roles in geotaxis of the three large chromosomes are described.
Previous studies have assumed Drosophila to be negatively geotactic and found this to be the case. New methods of observation now yield a spectrum of geotactic behavior both positive and negative. Two-way selection produces races of animals performing in diametrically opposite fashion to the same stimulus conditions.
