General Information

Term

abnormal dorsal/ventral axis specification

ID (Ontology)

FBcv:0000324 (FlyBase CV)

Definition

Phenotype that is any abnormality in dorsal/ventral axis specification (GO:0009950). 'dorsal/ventral axis specification' is defined as: 'The establishment, maintenance and elaboration of the dorsal/ventral axis. The dorsal/ventral axis is defined by a line that runs orthogonal to both the anterior/posterior and left/right axes. The dorsal end is defined by the upper or back side of an organism. The ventral end is defined by the lower or front side of an organism.'

Also Known As
