abnormal meiotic homologous chromosome biorientation
A cellular process phenotype in which homologous chromosome biorientation is abnormal during meiosis. 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.
