Effect of age and of screening pigment mutations on the phototactic behavior of Drosophila melanogaster.
Five different eye color mutations of Drosophila melanogaster have been tested for their effect on phototactic behavior. All five mutations seem to cause flies to be less photonegative than Canton-S control flies. The mutation sepia was found to produce this effect when heterozygous as well. It was also found that wild-type flies from highly photopositive and photonegative strains seem to be more photoneutral with age.
