متن کاملTetrazolium oxidase polymorphism in rainbow trout.
Tetrazolium oxidase from the blood and liver of rainbow trout was found to be genetically polymorphic. The inheritance pattern of the liver enzyme was compatible only with a one locus-two allele hypothesis. The enzymes in the blood while having an electrophoretically identical polymorphism could differ genotypically from that of the liver in a given fish. The significance of these findings to t...
متن کاملConserving Genetic Diversity in Rainbow Trout
Conserving genetic diversity is a major concern for north temperate fauna which are species poor but rich in genetic diversity. The problem is believed to be especially serious for freshwater fish where populations are isolated by barriers to migration. Isolation and low species diversity have been hypothesized to be the key ingredients in an adaptive radiation that has taken place in British C...

The triploid individuals were normal in size and external appearance, had underdeveloped gonads, and showed no evidence of 3n/2n chimerism or mosaicism.
