The position of the telomeric sequences in the chromosomal spreads, as revealed by FISH.

<p>ITSs in pericentromeric regions: <i>Chamaeleo calyptratus</i> (a), <i>Cordylus beraduccii</i> (b). ITSs in intermediate positions: <i>Trioceros bitaeniatus</i> (c), <i>Pantherophis guttatus</i> (d). ITSs in numerous positions: <i>Aspidoscelis deppei</i> (e), <i>Lialis burtonis</i> (f), <i>Cyrtopodion scabrum</i> (g), <i>Agamura persica</i> (h). Chromosomes are stained with DAPI (blue), while the FITC signal from the telomeric probe is red. Chromosomes with ITSs are indicated by arrows.
