The nuclear DNA content of 23 selachian species (10 Batoidea, 11 Galeomorphii, and 2 Squalomorphii) was histophotometrically studied. Their genome sizes range from 7.5 pg/N in Raja fillae (Batoidea) to 34.1 pg/N in Oxynotus centrina (Squalomorphii). Results show slight differences in the pattern of quantitative variations between the superorders Batoidea and Galeomorphii; Squalomorphii preserve their peculiar wide interspecific variability at the intrafamilial level, with values sited between… CONTINUE READING
