WBPhenotype:0000867
|
embryonic arrest
|
Cessation of development during any stage occurring after fertilization and until hatching compared to control. |
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:0001378
|
mitotic chromosome segregation variant
|
Any variation in the cell cycle process whereby replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle compared to control animals. |
WBPhenotype:0001216
|
meiosis metaphase to anaphase transition block
|
Oocyte chromosomes arrest in metaphase of meiosis I without transitioning to anaphase or producing polar bodies. |
WBPhenotype:0001743
|
mitosis variant
|
Any variation in the division of the eukaryotic cell nucleus to produce two daughter nuclei that contain the identical chromosome complement of their mother compared to control. |
WBPhenotype:0001130
|
cytokinesis fails early emb
|
Cells of the embryo attempt to divide but fail to form two daughter cells. |
WBPhenotype:0001159
|
pronuclear morphology defective early emb
|
Pronucleus morphology is atypical in the inviable embryo. |
WBPhenotype:0001147
|
polar body defective early emb
|
Polar bodies are abnormal in the inviable one- to four-cell embryo. |
