〔生〕（细胞减数分裂）终变期
Example sentencesExamples
- Their nuclei contain univalents as well as bivalents at diakinesis and metaphase I.
- 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.
- However, in the mouse, cytogenetic examination of chiasmata at diakinesis has been widely used to study genetic recombination.
- Loose condensation of chromosomes was observed in 12% of the cells from diakinesis to anaphase.
- In wild-type hermaphrodites, germ cells at the dorsoventral flexure exit the pachytene stage of the first meiotic prophase and proceed to diakinesis.

Origin

Early 20th century: from dia- 'through, across' + Greek kinēsis 'motion'.
