|
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. |

WBPhenotype:0000864
|
early elongation arrest
|
Cessation of development during the initial period of elongation. In C. elegans, this period refers to the conversion of the bean-shaped embryo into the two-fold- shaped embryo. |
|
WBPhenotype:0001492
|
no back end
|
Animals lack a properly developed posterior region compared to control. In C. elegans, mutants exhibit a severely deformed posterior region with a variable knob-like shape; accompanied by arrest at about the time of hatching with fairly normal pharyngeal and anterior development. Most mutants arrest as L1 larvae, and 5% do not hatch. |

|
lima bean arrest
|
Cessation of development at an intermediate stage in embryogenesis, immediately following the completion of gastrulation. In C. elegans this occurs around 350-390 minutes after first cleavage, cell number is at approximately 560 cells. At this time cell proliferation ceases and the embryo begins morphogenesis and elongation. The shape of the entire embryo within the eggshell resembles a lima bean (Wormatlas). |

|
embryonic arrest during gastrulation
|
Cessation of development during the gastrulation stage of embryonic development. In C. elegans, gastrulation occurs 100-290 minutes after first cleavage at 20 degrees Centigrade when the embryo develops from 28 cells to 421 cells (during the proliferating embryo life stage). |
