Detection of allelic variation within the growth hormone gene in common bream using heteroduplex analysis*

Abstract

A novel method, heteroduplex analysis, was applied for detecting variation in an amplified growth hormone ( GH ) gene segment of common bream Abramis brama . Two‐allele polymorphism was detected within a 262 bp restriction fragment. The frequency of the variant haplotype in the Main River was 0–50 and in the Danube River 0–32, but the difference was Statistically not significant.
