Résumé du livre
Protein variation was used to genetically characterize and measure the genetic variation of rainbow trout from the U.S. Fish and Wildlife Service's Fish Genetics Laboratory. Estimates are given for the levels of variation occurring both within the strains and among the strains. A comparison of these values and estimates of the amount of genetic variation within and among steelhead populations of the Columbia River drainage indicated that (1) the within strain variation is approximately the same for the two groups but that (2) the among strain variation of the Fish Genetics Laboratory strains is lower than that of the Columbia River steelhead. Genetic similarities were measured and are in the range expected for conspecific strains. The lowest similarities were exhibited by pairs that included New Zealand, the most divergent strain. Consideration is given to possible causes of the excessive number of genotype distributions that departed from Hardy-Weinberg proportions. Potential breeding and management applications of electrophoretically detected protein variations are discussed.
