Diakinesis The term coined by Häcker (1897) for the stage of late prophase 1 of meiosis when the chromosomes are well separated from one another (Gk. kinesis, movement; dia, apart). This stage is recognized by the highly condensed condition of the chromosomes, the homologous pair of which are held together by chiasmata. In some organisms, just before or during diakinesis the chiasmata move to the ends of the chromosom arms (terminalization of chiasmata). When there are interstitia chiasmata, the successive loops into which the chromosome-pair is divided are set in planes at right angles to one another.
