General Information

Term

meiotic metaphase chromosome alignment

ID (Ontology)

GO:0051311 (Gene Ontology)

Definition

A chromosome localization process whereby chromosomes are positioned in a specific order and orientation at the metaphase plate (spindle equator), during meiotic chromosome segregation. This alignment ensures that each daughter cell will receive the correct number of chromosomes during cell division.

Also Known As

"metaphase plate congression during meiosis"
