egg round

The overall structure or appearance of fertilized oocytes that are laid has every part of their surface equidistant from the center.

centrosome pair and associated pronuclear rotation variant

Any variation in the rotation of the centrosome-pronuclear complex after its migration toward the center of the embryo, compared to control.

centration defective early emb

The coordinated movement during prophase of the two centrosomes and the two pronuclei towards the center of the one cell embryo is abolished.

SM migration variant

Variations in the movement of sex myoblasts compared to control animals. In C. elegans, the larval SM migrate anteriorly to the precise center of the developing hermaphrodite gonad.

axoneme morphology variant

Animals exhibit variations in the structure or composition of the microtubule-based fibrillar bundle (axoneme) that makes up the core of the middle part of the cilium (in a pattern of nine doublet microtubules attached to the membrane and a variable number of smaller singlet microtubules occupying the center). In C. elegans, the axoneme microtubules are arranged in a pattern of nine doublets attached to the membrane with seven smaller singlet microtubules occupying the center.

missing gonad arms

Animals are missing one or both gonad arms, the normally U-shaped projections of the gonad that extend into the anterior or posterior of the animal and bends back towards the center of the animal.

astral microtubule asymmetry defective

There is significantly less difference between the number of astral microtubles or other component(s) of the spindle microtuble organizing center at the anterior versus posterior poles of the spindle, than observed in control animals.

centrosome biogenesis variant

Animals exhibit variations in the formation, maturation or disassembly of the centrosome (a subcellular body consisting of two centrioles embedded in a protein matrix). The centrosome serves as a microtubule organizing center as well as a regulator of cell-cycle progression.
