Population genetic structure of two abyssal grenadiers of the north Atlantic and northeastern Pacific oceans
I studied the population genetic structure of abyssal grenadier: Coryphaenoides armatus and Coryphaenoides yaquinae of the Pacific and Atlantic Ocean basins, testing the hypothesis that population genetic structure is detectable by microsatellite allele analysis. I determined allele frequencies at s...
