noun (plural diakineses /ˌdʌɪəkʌɪˈniːsiːz/)[mass noun] Biology
The fifth and last stage of the prophase of meiosis, following diplotene, when the separation of homologous chromosomes is complete and crossing over has occurred.
- For F59A1.7, affected worms exhibiting a high frequency of achiasmate chromosomes at diakinesis also had abnormally large nuclei at the pachytene stage, earlier in meiotic prophase.
- In wild-type hermaphrodites, germ cells at the dorsoventral flexure exit the pachytene stage of the first meiotic prophase and proceed to diakinesis.
- Loose condensation of chromosomes was observed in 12% of the cells from diakinesis to anaphase.
Early 20th century: from dia- 'through, across' + Greek kinēsis 'motion'.
