| Abstract: | In New Zealand chinook salmon Oncorhynchus tshawytscha , sexual genotype did not correspond to phenotype in 1·6% of male fish, contrasting starkly with North American chinook populations, where inconsistencies between female genotype and phenotype have been observed at frequencies up to 84%. |
