Chromosomes of Rhampsinitus leighi (2n=26) from Vernon Crookes (A, C–F) and from Silaka (B, G–M) after Giemsa staining (A–C, E, G, I, J, L) and after FISH with 18S rDNA (A and B partly, D, F, H, K, M). A, B karyotypes of males based on mitotic metaphase C, D pachytene with heterozygous bivalent (asterisk), bottom right inset shows a reconstruction of the heteromorphic bivalent E, F diplotene with heterozygous bivalent (asterisk) G, H mitotic prophase I diplotene, arrowheads indicate bivalents with two chiasmata. J, K diakinesis L, M one sister cell of metaphase II. White arrows indicate the position of 18S rDNA and black arrows indicate the same position after Giemsa staining. Asterisks indicate heteromorphic bivalent with large signal of rDNA. Bar = 10 μm.
