Term Information

Accession: GO:0045143
Name: homologous chromosome segregation
Ontology: biological_process
Synonyms: meiosis I, chromosome segregation
Alternate IDs: GO:0007061
Definition: The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the first division of the meiotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner; this pairing off, referred to as synapsis, permits genetic recombination. One homolog (both sister chromatids) of each morphologic type goes into each of the resulting chromosome sets. Source: ISBN:0815316194, GOC:ai
