Fig. (1) — Monocentric (a) and holocentric chromosomes (b) differ for the presence of a localized centromere. In view of diffuse kinetic activity, holocentric chromatids move apart in parallel and do not form the classical V-shaped figures typical of monocentric (c) and do not have a preferential localization of heterochromatin that can be present in different chromosomal areas, as showed by in situ hybridization with the Hind200 satellite DNA (d) and the subtelomeric repeat (e) probes on the holocentric chromosome of the aphid Myzus persicae.
