General Information
Term temperature conditional amorphic allele - genetic evidence ID (Ontology) FBcv:0000737 (FlyBase CV)
Definition An allele inferred to completely lack function at some temperatures (restrictive temperatures) but not others (permissive temperatures) from the observation that addition of extra copies in the genome has no effect on the phenotype at the restrictive temperatures. Most commonly, evidence takes the form of the observation that the phenotype of homozygotes (2 copies) is identical to that seen when the allele is in trans to a deletion of the gene (1 copy).[ FlyBase:FBrf0002371 FlyBase:FBrf0049147 ]
