Syntenic relationships among several chromosome pairs of <i>Hylaeamys megacephalus</i> (HME), <i>Akodon montensis</i> (AMO), <i>A</i>. <i>paranaensis</i> (APA), <i>Thaptomys nigrita</i> (TNI), and <i>Cerradomys langguthi</i> (CLA) reveled by different chromosome-paint probes (Adapted from Hass et al [15, 16], Ventura et al. [12], and Nagamachi et al. [17]).

Ideograms of <i>Akodon montensis</i> (A), <i>Thaptomys nigrita</i> (B), and <i>Cerradomys langguthi</i> (C), showing chromosome homologies to <i>Hylaeamys megacephalus</i> (left black numbers) and <i>Akodon paranaensis</i> (right green numbers).

<p>Red stars show regions without complementarity with the probes used. Scale shows the percent relative size of chromosome pairs. (Adapted from Ventura et al.

Hybridization <i>in situ</i> experiments with chromosome-specific probes of <i>Hylaemys megacephalus</i> hybridized to metaphase chromosomes of <i>Akodon montensis</i> (a, b, c, d and e) and <i>Thaptomys nigrita</i> (f) showing syntenic associations.
