Term neomorphic allele - genetic evidence ID (Ontology) FBcv:0000291 (FlyBase CV)
Definition An allele that is inferred to make a gene product with a novel function or expression pattern compared to wild-type based on the evidence that the phenotype is unaffected by extra or fewer doses of the wild-type gene.[ FlyBase:FBrf0002371 FlyBase:FBrf0049147 ]
