Term summary

ID

FYPO:0005641

Name

abnormal chromosome segregation during meiosis I with premature sister kinetochore separation, lagging chromosomes, and normal chromosome separation

Ontology or CV name

Phenotype

Definition

A cellular process phenotype in which kinetochores become separated during the first meiotic nuclear division, and in which homologous chromosomes do not move towards the spindle poles at the same time during anaphase, but are eventually separated normally.

Parents
