Phenotype ontology term - FYPO:0008189 - equational sister chromatid segregation during achiasmatic meiosis I

Term summary

ID

FYPO:0008189

Name

equational sister chromatid segregation during achiasmatic meiosis I

Ontology or CV name

Phenotype

Definition

A cellular process phenotype in which sister kinetochores become separated during the first meiotic nuclear division, and sister chromatids subsequently separate to result in equational segregation, only visible in the absence of chiasmata. Equational sister chromatid separation is caused by bi-orientated attachment of sister chromatids.
