The sex-linked gene, tuh-1, produces a maternal effect that is associated with the tumorous head abnormality in Drosophila melanogaster. With the aid of various known deletions, tuh-1 has been localized to band 20A1-2 on the salivary chromosome map of the X.
The extent of neurogenesis in Drosophila is under the control of the so-called neurogenic genes, named for their mutant phenotype of causing neural hyperplasia. Their wild-type products appear to be responsible for a signal chain that decides the fate of ectodermal cells in the embryo. Various kinds
