Cytogenetics of Atlantic eels: C- and G-banding, nucleolus organizer regions, and DNA content

Abstract
C- and G-banding, silver staining, and cytofluorometric analysis of DNA content were carried out on two species of eels, Anguilla anguilla and A. rostrata, to compare them, to investigate the existence of sex chromosomes in both species, on which different authors disagree, and to understand the significance of the sex-independent variability found in one chromosome pair.
