dorsal medial muscle & synapse (with cacTS2)
General characteristics of mutant phenotype (heterozygous with a viable allele): Song pulse - mutant; Optomotor test - mutant; CC-phototaxis - mutant; Y-phototaxis - mutant; ERG transients - mutant; ERG LCRP amplitude - mutant; ERG LCRP kinetics - mutant; ERG Rebound - mutant; ERG refractory wandering - mutant.
Song pulse amplitude in heterozygotes with cac1 is higher than wild type.
Extensive phenogenetic analysis of allelic combinations reveals a phenotypic series for visually mediated behaviors and genetically separable ERG defects and courtship song defects.

Maternal germline clonal analysis demonstrates there is no maternal effect.
