| Remarks |
Probes (CA)15 and (GA)15 exhibited same general pattern, terminal markings in both arms of all chromosomes, except for metacentric pair 11, which showed interstitial signals in short arm with both probes. The distinctive markings obtained with microsatellites were consistently observed in both sexes |
