Overview of the five phenotypic categories identified. Phenotypic classes based upon FMRFa-eGFP expression among the identified mutants. From a total of 9781 mutant chromosomes, 325 and 286 mutants affecting FMRFa-eGFP expression were identified on the second and third chromosomes, respectively. The mutants were grouped into five categories based upon eGFP expression. The main part of the mutants showed none, weak, or variable eGFP expression. A small number of mutants (24 on the second chromosome and 2 on the third chromosome) instead expressed eGFP in an excess number of neurons. “Other phenotypes” refers to mutants with malformed embryos or other unspecific phenotypes.
