1929 C. D. Darlington in Jrnl. Genetics 21 266 The post-diplotene stages in this species are characterised by a regular movement of chiasmata towards the attachment constriction. The opposite movement, which I will call ‘terminalisation’, affords a sufficient and indeed the only explanation of the exceptional metaphase configurations found in Tradescantia.

1964 Q. Rev. Biol. 39 267/1 A very long dictyotene stage..might cause so complete a terminalization of chiasmata that in the first meiotic anaphase the bivalents of a tetrad would be likely to lead to disturbed separation and to non-disjunction.

1979 Nature 22 Mar. 349/2 The issue of terminalisation is relevant both theoretically (assessment of chiasma and crossover frequency) and practically (alleged factor in maternal-age-dependent non-disjunction in mammals).

2010 Plant Cell 22 426/1 The phenomenon of chiasma terminalization varies remarkably in different organisms.
