title: The time of action of three mutations affecting Drosophila eye morphogenesis.
abstract: Histology and clonal analysis are used to look at the time of action of the mutant Drosophila genes eyeless, eyeless dominant and sine oculis. The findings suggest that eyeless dominant has its effect during the first two larval instars, whilst eyeless and sine oculis act during the third larval instar.
