WBPhenotype:0000286
|
embryo disorganized
|
Embryos fail to be organized in the same manner as observed in control animals. |
|
WBPhenotype:0000867
|
embryonic arrest
|
Cessation of development during any stage occurring after fertilization and until hatching compared to control. |
|
WBPhenotype:0000050
|
embryonic lethal
|
Animals die during embryonic development. In C. elegans, often assayed as refractile eggs that fail to hatch; when applied to large-scale RNAi screens in C. elegans, more than 10% of embryos die. |
|
WBPhenotype:0000042
|
slow embryonic development
|
The progression through stages between fertilization to hatching are temporally retarded. |
|
WBPhenotype:0000034
|
embryonic polarity variant
|
Contents or structures of an embryonic cell are not restricted/localized to the same positions (or poles) compared with control animals. |
|
WBPhenotype:0000047
|
gastrulation variant
|
Variations in the process by which the germ layers become positioned in an embryo compared to control animals. Gastrulation involves the proper ingression of small groups of cells at various times into the blastocoel space. |
|
WBPhenotype:0001566
|
ventral enclosure variant
|
Any variation in the process that regulates the migration of ventral epidermal cells toward the ventral midline (to encase underlying cells in an epithelial monolayer) in developing embryos compared to control. |
|
WBPhenotype:0001478
|
body elongation variant
|
Any variation in the elongation of embryonic epidermal cells compared to control. In C. elegans, this elongation occurs along an anterior-posterior axis, which is required to transform the bean-shaped embryo into the elongated shape of the worm. |
|
WBPhenotype:0000472
|
endoderm absent
|
Animals lack the early blast cells that give rise to the gut tissue (Wormatlas). |
|
WBPhenotype:0001062
|
late paralysis arrested elongation two fold
|
In C. elegans, movement and elongation stop nearly simultaneously soon after the twofold stage of elongation. However, mutant embryos twitch at the one-and-a-half-fold stage of elongation, like control animals, and move as well as control animals at the two- fold stage. |
|
WBPhenotype:0000048
|
hatching variant
|
Variations in the ability of an animal to emerge from the protective egg shell compared to control animals. |
|
WBPhenotype:0008001
|
embryonic cell fate specification variant
|
Any variation in the processes that govern acquisition of particular cell fates in the embryo, from the time of zygote formation until hatching compared to control. |
|
WBPhenotype:0000764
|
embryonic cell organization biogenesis variant
|
Variations in the processes that are carried out at in the embryo which results in its formation or the arrangement of constituent parts, compared to control. |
|
WBPhenotype:0001812
|
embryonic rupture
|
During development of the embryo, the epidermis loses integrity and the contents of the embryo are expelled. |
|
WBPhenotype:0001521
|
body elongation retracted
|
Embryos retract after the embryonic elongation process. |
|
WBPhenotype:0000161
|
nuclear rotation variant
|
Any variation in the rotation of centrosomes and associated pronuclei in one-cell embryo, occurring as a transition between pronuclear migration and pronuclear fusion compared to control. |
|
WBPhenotype:0000213
|
zygotic development variant
|
Variations in the progression of a zygote from formation (gamete fusion) to just prior to the first cell division compared to control. |
|
WBPhenotype:0000051
|
embryonic terminal arrest variable emb
|
The developmental program does not continue past embryogenesis; stage of arrest is not consistent from animal to animal. |
|
WBPhenotype:0000374
|
early divisions prolonged
|
The time interval in which early embryonic cell divisions occur is increased compared to control. |
|
WBPhenotype:0000375
|
later divisions prolonged
|
The time interval in which late embryonic cell divisions occur is increased compared to control. |
