Analysis of 570 nucleotide sequences of the mitochondrial r16S gene of four species of silversides “peces blancos” (Chirostoma sp.) and of two euryhaline related species Membras martinica and Menidia menidia indicated variation that aided in development of a DNA-based method for species identification. The nucleotide sequence data showed levels of inter-generic genetic variation that ranged from 3...
