1912 Jrnl. Acad. Nat. Sci. Philadelphia 15 525 The most general results of increased temperature are:... (4) Formation of numerous karyomeres from these scattered chromosomes; indeed by slight increase of temperature almost every chromosome may be caused to remain distinct from every other one, and to give rise to a separate chromosomal vesicle.
1920 W. E. Agar Cytol. 130 The chromosomes of the spermatogonial telophases do not come into contact at all, but each one forms a separate little nucleus, or karyomere, by itself.
1934 L. W. Sharp Introd. Cytol. (ed. 3) x. 136 Of considerable interest are those nuclei in which every chromosome of the telophase group forms an individual vesicle, or karyomere. In some cases the karyomeres may eventually fuse partially or completely, but in others they remain separate although in contact, forming what is virtually a group of small nuclei containing one chromosome each.
1934 L. W. Sharp Introd. Cytol. (ed. 3) x. 146 The limits of the several chromosomes remain visible through this stage [sc. between mitoses] in certain nuclei; in extreme cases the nucleus is virtually a group of separate elementary nuclei, or karyomeres.
1969 W. V. Brown & E. M. Bertke Textbk. Cytol. xvii. 318/2 Karyomeres are rather like micronuclei except that they are normal and become associated to form a ‘compound’ nucleus.
