S. Salvadori et al., Cytogenetic and molecular characteristics of Atlantic eels (Anguilla anguilla and A-rostrata) genome, ITAL J ZOOL, 65, 1998, pp. 61-64
The Atlantic eels, Anguilla anguilla and A. rostrata, have partially overla
pping spawning sites and show incomplete reproductive isolation as testifie
d by the presence of hybrids at low frequency. Nevertheless, significant ge
netic differences between the two spec-its have been pointed out by data on
biochemical polymorphisms and mitochondrial DNA. This study reviews the cy
togenetic and molecular data and points out differences and similarities be
tween the two species.
