A GENETIC ANALYSIS OF PHOTOTACTIC BEHAVIOR IN DROSOPHILA MELANOGASTER I. SELECTION IN THE PRESENCE OF INVERSIONS

1 Department of Zoology, Arizona State University, Tempe, Arizona 85281

The effectiveness of selection for positive and negative phototactic behavior in populations of Drosophila melanogaster heterozygous for various multiple inversions was compared using the method of realized heritability. Selection in the presence of FM6, SM1 or TM3 alone was as effective as in populations carrying no inversions. However, the presence of FM6 and TM3 together reduced the effectiveness of selection for photopositive behavior and FM6 and SM1 and TM3 restricted the response to selection for negative phototactic behavior. The results are discussed in terms of the organization of genes influencing phototactic behavior in this species.
