Micron, 2011
Secondary constrictions or 45S rDNA sites are commonly reported to be located mainly in the terminal regions of the chromosomes. This distribution has been assumed to be related to the existence of a "chromosome field" lying between the centromere and the telomere, an area in which certain cytogenetic events may predominantly occur.

Chromosoma, 1982
During micronuclear mitosis of the heterotrichous ciliate Nyctotherus ovalis Leidy rod-shaped composite chromosomes are formed by lateral association of telokinetic chromosomes. The formation of these composite chromosomes seems to be a highly ordered process since only nuclei with either 18 or 24 such chromosomes can be observed, and nuclei with the ...

Chromosomes and nucleoli in the karyomeres of cleavage eggs of the arrhenotokous spidermiteTetranychus urticae Koch were treated with a silver-staining procedure for nucleolar material to establish the number of nucleoli and of the chromosomes that produce them.

Chromosomes of the holokinetic organization type were irradiated with X-rays in various stages of meiosis in unfertilized eggs of Tetranychus urticae Koch. Visible cytological aberrations, lethality and sterility were investigated in subsequent generations.
