Examples of fluorescent <i>in situ</i> hybridization.

<p>a—localization of telomeric DNA probe (red) and rDNA probe (green) on metaphase chromosomes from <i>C</i>. <i>porcellus</i>; telomeric signals are too weak to capture without risking over-exposure to the strong signals from pericentromeric regions; b—HSA19 (green) and CPO6+7 (red) on metaphase chromosome from <i>C</i>. <i>porcellus</i>; c—CPO26 (green) and CPO19 (red) on metaphase chromosome from <i>H</i>. <i>sapiens</i>; d—HSA22 (green) and CPO14+16 (red) on metaphase chromosomes from <i>C</i>. <i>porcellus</i>; e—HSA20 (green) and CPO6+7 (red) on metaphase chromosomes chromosome from <i>C</i>. <i>porcellus</i>; f—CPO14 on metaphase chromosomes from <i>H</i>. <i>sapiens</i>. Arrows indicate the corresponding human chromosomes in 4b, 4d, 4e and the corresponding <i>C</i>. <i>porcellus</i> chromosomes in 4c and 4f. Scale bars indicate 10 μm.
