- n. Plural form of univalent.
Sorry, no etymologies found.
All 40 chromosomes of mouse oocytes are telocentric, so homologs form bivalents in meiosis I while sister chromatids form univalents in meiosis II
Until MII, the oocytes always showed premature separated chromatids, while in control, sister chromaitids as univalents did not separate (
Very notably, in some oocytes with PBE, which indicates that the APC / C activity and onset of anaphase are normal, bivalents consisting of homologous chromosomes were seen instead of univalents as in the control (
Centromeres between sister chromatids lost the protection from Sgo1 and linkage between chromatids was degraded, and thus single chromatids instead of univalents was found (
