Mitochondrial DNA Diversity and Population Structure in Marine Fish Species from the Gulf of Mexico
Variation in mitochondrial DNA (mtDNA) was examined among 693 red drum (Sciaenops ocellatus), 300 black drum (Pogonias cromis), and 421 red snapper (Lutjanus campechanus) sampled from several localities in the Gulf of Mexico. The number of mtDNA genotypes (haplotypes) observed were: 99 in red drum,...
