The congruence between secondary sexual characters and molecular markers, linked to the Ychromosome was examined in Asian populations of five Pacific salmon species of the genus Oncorhynchus. Our results support the existence of discrepancy between secondary sexual characters and sex-linked molecular markers in all species examined, which suggests the existence of similar or identical mechanism responsible for this phenomenon in Pacific salmons. Clinal latitudinal directional variation of the character confirmed the possibility that this phenomenon could be adaptively important, including its importance for regulation of the population number. In addition to natural factors affecting the degree of discrepancy between morphobiological characters and molecular markers in the Pacific salmon populations, anthropogenic factors, in particular intense fishery of certain population or population group, is also important.
