- oocyte accumulation
An increased number of oocytes are retained in the gonad without becoming endomitotic, compared to control.
- rubber band
When prodded on the head, worm contracts and then relaxes along its entire body without moving backwards, compared to a control worm which contracts its anterior end and backs away in response to prodding.
- endoreduplication variant
Any variation in the multiple rounds of DNA replication that take place without chromosome condensation, segregation or cytokinesis compared to control. In C. elegans this process is normally seen in intestinal nuclei during each larval lethargus which results in adult intestinal nuclei with 32 copies (32C) of each chromosome(Wormatlas).
- biofilm absent head
Animals can move thorough a lawn of bacterially produced biofilm without accumulating an enormous amount of biofilm on its nose. When C. elegans is exposed to certain bacteria (e.g., Y. pestis), a biofilm accumulates on a worm's head. The presence of this biofilm inhibits feeding by the worm, and thereby prevents growth.
- over retracted male tail
Adult males exhibit a truncated tail, often without a fan or have well-developed fans but squarish, truncated back ends compared to control. In C. elegans this is due to precocious male tail tip retraction beginning in the early L3 stage (normally retraction begins in the L4 stage). Condition can be lethal if the function of the anus is affected.
