Missing parent:resolution of meiotic recombination intermediates (GO:0000712) #25628

Closed ValWood closed 1 year ago

but should probably be homologous chromosome segregation (GO:0045143)?

The parent term

GO:0007131 reciprocal meiotic recombination The cell cycle process in which double strand breaks are formed and repaired through a single or double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity. PMID:2087779

Since meiotic recombination is responsible for chiasmata formation, should it be part_of homologous chromosome segregation, OR should only the "chiasmata formation/assembly" term be part of homologous chromosome segregation?

ValWood commented 1 year ago

To make consistent, since GO:0007131 reciprocal meiotic recombination does not have the parent "meiotic chromosome segregation" I will remove this parent from :resolution of meiotic recombination intermediates (GO:0000712)

At present, I'm going to consider chiasmata assembly as an output of reciprocal recombination and a part of homologous chromosome segregation, but not recombination itself. Once all the other fixes are in place I can check this with the experts.
