General Information
Term meiotic metaphase I homologous chromosome alignment ID (Ontology) GO:0043060 (Gene Ontology)
Definition A cell cycle process whereby homlogous chromosomes are positioned in a specific order and orientation at the metaphase plate (spindle equator) by the spindle machinery and centromere/kinetochore arrangement during meiosis I chromosome segregation. This alignment ensures that each daughter cell will receive the correct number of chromosomes during cell division.[ PubMed:10809666 ]
Also Known As"meiotic metaphase I chromosome alignment"
