Chromosomes of Guruia africana (2n=24) males after Giemsa staining (A–E) and after FISH with 18S rDNA (A partly, F–I). A karyotype based on mitotic metaphase B pachytene C diplotene D diakinesis E one sister cell of metaphase II F–I are the same cells as B–E after FISH with 18S rDNA. White arrows indicate the position of 18S rDNA and black arrows indicate the same position after Giemsa staining. Bar = 10 μm.
