one point five fold arrest emb

Cessation of development that normally occurs in C. elegans 420-460 min after the first embryonic cleavage at 20C, the stage between the comma and 2-fold embryo.

two fold arrest

Cessation of development that normally occurs in C. elegans 460-520 min after the first cleavage at 20C, the stage between the 1.5-fold and 3-fold embryo.

late embryonic arrest

Cessation of development during the final stages of embryogenesis. In C. elegans, this stage normally occurs 620-800 min after the first cleavage at 20C and is the stage after elongation.

embryonic lethal late emb

Animals die during the final stages of embryogenesis. In C. elegans, this lethality refers to death during the last (3-fold) stage of embryogenesis, which normally occurs 620-800 min after the first cleavage at 20C, the stage after elongation.

gonad degenerate

Animals contain a gonad that initially functioned, but subsequently stopped. In hermaphrodites or females there is often the presence old embryos and/or hatched larva, but no young embryos, in the uterus.
