| Remarks | 5S rDNA signals located on three chromosomal sites: in pericentromeric regions of short arms of chromosome pairs 2 and 25, and a subterminal site on acrocentric 21. The 18S rDNA sites evidenced signals on subterminal region of short arms of chromosome pair 25, syntenic with 5S rDNA sites. |
