Abstract
Abstract Mitochondrial DNA (mtDNA) variation was examined for two nominal subspecies of largemouth bass, Micropterus salmoides salmoides (northern largemouth bass) and M. s. floridanus (Florida largemouth bass). Mitochondrial DNA nucleon diversity values within samples ranged from 0.378 to 0.911; the value over all individuals surveyed was 0.917. Estimated percentage nucleotide sequence divergence among the 19 haplotypes ranged from 0.081 to 5.80 (mean ± SE, 2.72 ± 0.459). The average percentage nucleotide sequence divergence within populations ranged from 0.137 to 0.526 (mean ± SE, 0.312 ± 0.067). The average percentage nucleotide sequence divergence among pairwise comparisons of populations ranged from 0.174 to 5.11 (mean ± SE, 2.91 ± 0.523). Parsimony and phenetic analysis of populations yielded strong differentiation between the two subspecies and provided enough resolution to discriminate among populations within the same subspecies. These data suggest that restriction fragment length polymorphism (R...
