Abstract

Although the copepod crustaceans have been studied for more than 200 years, the freshwater forms have always been less intensely studied than their marine counterparts and little is known of their genetics. This is especially true in North America, where few studies have aimed to advance knowledge of the systematics and evolution of this group. This study investigated 24 North American species within 2 orders in the Copepoda, representing a substantial proportion of the known fauna. Biochemical variation was best explained by simple Mendelian segregation of alternate alleles and from 12.5% to 53.2% of loci were polymorphic with 1.12-2.0 alleles per locus on average. The genetic variation was unaffected by sex linkage, autosomal linkage disequilibrium or four important physical parameters (absorbance
