ID (Ontology)

FBbt:00000153 (Fly Anatomy)

Definition

Embryonic metameric unit comprising the posterior compartment of abdominal segment 9 and the anterior compartment of abdominal segment 10.[ FlyBase:FBrf0049804 FlyBase:FBrf0051565 FlyBase:FBrf0089570 ]

Comment

Definition added based on definitions for other parasegment definitions. Parasegment 14 is the most posterior parasegment mentioned in the original parasegment paper (Martinez-Arias and Lawrence, 1985), but subsequent papers (e.g.- Celniker et al., 1989, Mlodzik et al., 1990) refer to parasegment 15, and Campos-Ortega and Hartenstein (1997), refer to two parasegments posterior to parasegment 14 defined by homeotic gene expression.
