Figure 4From: Cytogenetic studies in Eigenmannia virescens (Sternopygidae, Gymnotiformes) and new inferences on the origin of sex chromosomes in the Eigenmannia genusKaryotypes of Eigenmannia virescens : (A & C) DAPI banding consistent with the centromeric C-bands found in both male and female chromosomes. Note the bright staining of the W chromosome. (B & D) CMA3 banding of pair 15, consistent with our localization of the NOR. (E) FISH with rDNA 45S probes in E. virescens metaphase spreads. (F) FISH with telomeric probes in E. virescens metaphase spreads. No evidence of ITS was observed.Back to article page
