1652 Severall Proc. Parl. No. 149. 2331 The chiefe Ring-leaders, who being demanded the reason for their non-conjunction, produced a paper which was read in presentia by Wareston, disclaiming and protesting against the lawfulnesse of this Assembly.

1671 R. McWard True Non-conformist 490 Having solemnly vowed a detestation thereof, and a non-conjunction with all their bettors.

a1772 E. Swedenborg Heaven & its Wonders (1872) 200 That marriages between those who are of different religions are unlawful, on account of the non-conjunction of similar good and truth in the interiors.

1925 J. Belling in Jrnl. Genetics 15 256 Non-conjunction. This term is used instead of non-conjugation, because in most cases it cannot be told whether conjugation, that is, parasynapsis, has taken place or not, with regard to the chromosome pair in question... Non-conjunction cannot be distinguished from true non-disjunction, in the later stages.

1947 Proc. National Acad. Sci. U.S.A. 33 165 Frequent occurrence of non-conjunction or non-disjunction followed by irregular distribution of chromosomes.

1988 Philos. Trans. (Royal Soc.) B. 322 133 In man, failure of synapsis and chiasma formation within the pairing segment leads to non-disjunction (or non-conjunction) of the sex chromosomes and the production of sterile individuals.

3. Logic. The relation of the terms in a proposition asserting the negative of a conjunctive proposition (‘not both——and——’). Cf. Sheffer stroke at Sheffer n.

1926 H. M. Sheffer in Isis 8 229 The authors consider one of the cardinal improvements in the new edition to consist in their substitution, for the two operations of propositional negation and disjunction, of the single operation of non-conjunction.

1965 G. E. Hughes & D. G. Londey Elements Formal Logic viii. 54 The following are valid: (i) (p ↑ q) ≡ ∼ (p.q), (ii) (p↓ q) ≡ ∼ (p ∨ q), which suggests the names ‘non-conjunction’ and ‘non-disjunction’ for ‘↑’ and ‘↓’ respectively.
