WBPhenotype:0000777
|
polar body extrusion defective early emb
|
Unextruded or resorbed polar body(ies) leading to an extra PNs in P0 and/or extra karyomeres in AB/P1. |
|
WBPhenotype:0000775
|
meiosis variant
|
Variations in the specialized nuclear and cytoplasmic divisions of a single diploid cell, whose specific outcome is the formation of four haploid daughter cells compared to control. Meiosis occurs during the formation of gametes. |
|
WBPhenotype:0000773
|
chromosome segregation variant
|
Any variation in the processes that regulate the apportionment of chromosomes to each of two daughter cells compared to control. |
|
WBPhenotype:0001499
|
meiotic chromosome segregation variant
|
Variations in the process by which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets during the meiotic cell cycle, compared to control. |
|
WBPhenotype:0000040
|
one cell arrest early emb
|
Embryos fail to divide and arrest as one-cell embryos. |
|
WBPhenotype:0000372
|
no polar body formation
|
Animals lack the two small cells produced, each during one of the two meiotic cell divisions (Wormatlas). |
|
WBPhenotype:0001143
|
multiple nuclei early emb
|
Embryos contain more than one nucleus per cell in the inviable one- to four-cell embryo. |
