Modisiminae, males, detection of NORs (FISH). Arrowhead = NOR bearing chromosome (a) or bivalent (b), asterisk = centromere, open arrowhead = sex chromosome-linked NOR, X=X chromosome. a Psilochorus californiae (X0), mitotic metaphase. Chromosomes of one metacentric pair contain a terminal NOR. X chromosome bears NOR at both ends; b P. pallidulus (X0), metaphase I. One bivalent includes a tiny NOR. X chromosome has two terminal NORs. Bar = 5 µm
