Abstract
A secondary mechanism by which an autosomal, semidominant, and sex-linked recessive gene controlling a maternal effect specify abnormal head growth in the Utah State University tumorous-head strain of Drosophila melanogaster is under investigation. A model that predicts abnormal developmental commitments in the antenna-eye imaginal disc complex of late third instar larvae has been developed. The model reflects wide variability in abnormal expression through ten distinct morphological groups which are derived from key modifications of sequential developmental pathways determined in the early embryo. Homoeosis, the temperature sensitive period, cellular degeneration, and specific aldehyde oxidase activity are described by the model. The relationship of larval groups to similar morphological groups in the adult and loss of expressivity during pupation are also discussed.
