Isozyme Analysis for a Wild Population of Roughskin Sculpin,Trachidermus fasciatus,from the Yalu River Basin in China
TLDR
The results showed that the polymorphic loci and average heterozygosity of Roughskin Sculpin, a wild population from the Yalu River basin by vertical polyacrylamide gel electrophoresis is lower than the corresponding values of other kinds of fish having a similar living habit, which gives rise to discuss of the relationship of status of germplasm resources and the ecological environment.
