General Information
Term heat sensitive antimorphic allele - genetic evidence ID (Ontology) FBcv:0000765 (FlyBase CV)
Definition An allele inferred to make a gene product that is antagonistic to the wild-type gene product at high temperatures (restrictive temperatures) but not at lower temperatures (permissive temperatures) from the observation that, at the non-permissive temperatures, the phenotype over a deficiency is stronger than that over a wild-type allele, which in turn is stronger than that in the presence of a duplication of the wild-type locus.[ FlyBase:FBrf0002371 FlyBase:FBrf0049147 ]
