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
