Inheritance of orange pigmentation and scale pattern in common carp (Cyprinus carpio L.)

The aim of this study was to identify the type of genetic determination of orange pigmentation and scale pattern in carp. The parental fish used in the experiment were obtained from crossing two breeding strains, i.e., the Polish Starzawa S strain with scaled phenotype and normal pigmentation and the Hungarian strain C with mirror scale pattern and orange pigmentation. The mating of the two parental pairs resulted in four groups of F1offspring that were reared in ponds. It was observed that the two traits were inherited independently. Two pairs of alleles at two gene loci determined fish pigmentation. The orange fish were double recessive aacc homozygotes. All of the spawners used in the experiment were double heterozygotes with respect to color and scaliness SsnnAaCc. *
