Various stages of mitotic and meiotic Cimex lectularius chromosomes with basic karyotype 2n = 26+X1X2Y (A, B, D–L) and karyotype 2n = 26+X1-10Y (C), stained with Giemsa. A Mitotic prometaphase ♂ B Mitotic metaphase ♂ C Metaphase I ♂ D Leptotene ♀ E Pachytene ♀ F Diffuse stage ♂ G Diffuse stage - postpachytene transition ♂ H Postpachytene ♂ I Late postpachytene ♂ J Prometaphase I ♂ K Metaphase I ♂ L Metaphase II ♂. Arrow = sex chromosome (F, G, L) or fragments of supposedly sex chromosomes (C). Scale bar = 5 μm.
