| phylogenetic relationships among robertsonian karyomorphs of graomys griseoflavus (rodentia, muridae) by mitochondrial cytochrome b dna sequencing. | graomys griseoflavus (waterhouse 1837) is a phyllotine murid rodent with a robertsonian autosomal polymorphism, having been described 2n = 42, 41, 38, 37, 36, 35 and 34 karyomorphs, and proposed a chromosomal divergence pathway accounted by four sequential robertsonian fusions. sequences of a fragment (422 bp long) of the cytochrome b (cyt b) mitochondrial gene and its 5' flanking region (trna glu) were obtained for 19 graomys griseoflavus from different karyomorphs to infer phylogenetic relatio ... | 2002 | 12369098 |
