Term summary

ID

FYPO:0005642

Name

abnormal meiotic homologous chromosome biorientation with abnormal kinetochore orientation

Ontology or CV name

Phenotype

Definition

A cellular process phenotype in which homologous chromosome biorientation is abnormal during meiosis, with chromosomes that are not correctly oriented with the kinetochores facing outwards. Homologous chromosome biorientation is the process in which the sister centromeres of one chromosome attach to microtubules that emanate from the same spindle pole, ensuring that homologous maternal and paternal chromosomes are pulled in opposite directions at anaphase of meiosis I.
