Loss of tramtrack gene activity results in ectopic R7 cell formation, even in a sina mutant background.

Proceedings of the National Academy of Sciences of the United States of America - 14 May 1996

Abstract excerpt

We have screened a collection of transposable-element-induced mutations for those which dominantly modify the extra R7 phenotype of a hypomorphic yan mutation. The members of one of the identified complementation groups correspond to disruptions of the tramtrack (ttk) gene. As heterozygotes, ttk alleles increase the percentage of R7 cells in yan mutant eyes. Just as yan mutations increase ectopic R7 cell...
