title: Effect of age and of screening pigment mutations on the phototactic behavior of Drosophila melanogaster.
abstract: 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.
