noun

Biology
  • [mass noun] The fourth stage of the prophase of meiosis, following pachytene, during which the paired chromosomes begin to separate into two pairs of chromatids.

    • ‘RAD51 foci disappeared in both genotypes at late pachytene just before diplotene.’
    • ‘Surprisingly, most gld - 2; gld - 3 germ cells arrested in pachytene, a synthetic phenotype suggesting redundancy for progression into diplotene (data not shown).’
    • ‘In common snook, the germinal epithelium is active throughout the year, producing follicles where the oocyte is in arrested meiosis, diplotene of the first meiotic prophase, and the germinal epithelium is always discontinuous.’
    • ‘A small portion of the distal end of the long arm is asynapsed, indicating that the SC has begun desynapsis and is in the earliest stage of diplotene.’
    • ‘Marked RNA synthesis occurs in the tapetal cells at all stages of meiosis with a peak at diplotene, indicating that long before the tapetum begins to disintegrate it acquires a complex set of specifications in the form of mRNAs.’
