Most heterochromatic blocks appeared pale and were located at the terminal regions; however, some pericentromeric blocks were also observed in pairs 2m, 6m, and 17sm, and centromeric blocks were evident in pairs 1m, 4m, 5m, 18sm, and 20sm (Fig. 2B). Fluorescent in situ hybridization (FISH) with 18S rDNA probes revealed markings at the terminal positions on the long arm of pair 17sm in all analyzed specimens (Fig. 3A). Additionally, three individuals (two males and one female) exhibited an additional 18S rDNA site on a single chromosome of pair 7m, located at the terminal position of its short arm (Fig. 3A, in box). No specimen in our sample exhibited two pairs completely marked (four chromosomes) with the 18S rDNA probes. The AgNORs were coincident with the 18S rDNA sites on pair 17 (Fig. 2A, in box). FISHs with 5S rDNA probes showed this cistron is located at the proximal position of the short arm at the pairs 8m and 10m (Fig. 3A). FISH with the telomeric sequence (TTAGGG) n revealed markings exclusively at the terminal regions, with no presence of interstitial telomeric sites (ITS) (Fig. 3B).</p></div>	https://treatment.plazi.org/id/48359F06FF9A5D3AFE4D007FF1DA9C3E	Public Domain	No known copyright restrictions apply.
