Inferring Diversity and Evolution in Fish by Means of Integrative Molecular Cytogenetics

<div>(a)<i> Astyanax scabripinnis</i> pachytene elements subjected to double FISH with 18S ribosomal DNA probe (green) and those of the<i> As</i>51 repetitive sequence (red). These sequences are interspaced, showing syntenic and syntopic location, and present highlighted broad B chromosome distribution. The total length of each element is expressed in <i>μ</i>m. (b) Detail of the extended chromatin fiber subjected to double FISH showing the syntenic and syntopic colocation of 18S and<i> As</i>51 sequences. Bar = 10 <i>μ</i>m.</div>
