Phenotype ontology term - FYPO:0005633 - sister kinetochore dissociation in meiotic metaphase I, normal chromosome segregation in meiosis I, and sister chromatid non-disjunction in meiosis II

Term summary

ID

FYPO:0005633

Name

sister kinetochore dissociation in meiotic metaphase I, normal chromosome segregation in meiosis I, and sister chromatid non-disjunction in meiosis II

Ontology or CV name

Phenotype

Definition

A physical cellular phenotype in which sister kinetochores separate during the first meiotic nuclear division, homologous chromosomes undergo normal reductional division, but sister chromatids divide unequally in meiosis II. Normally sister kinetochores remain together until meiosis II. Normally sister kinetochores remain together until meiosis II.

Parents
