General Information
Term temperature conditional hypermorphic allele - genetic evidence ID (Ontology) FBcv:0000781 (FlyBase CV)
Definition An allele inferred from genetic evidence to make a normal gene product at increased levels or with increased activity compared to wild-type, where this increased amount or activity is present at some temperatures (non-permissive temperatures) but not others (permissive temperatures), and where the genetic evidence consists of the observation that extra copies in the genome increase the expressivity and/or penetrance of the phenotype at the non-permissive temperatures.[ FlyBase:FBrf0002371 FlyBase:FBrf0049147 ]
