Based on comparative genomics five candidate genes for pigmentation were chosen for analyses. None of them proved to be linked with marble color pigmentation. SNPs in five genes were tested on different marble and brown trout populations and all of them turned as diagnostic for differentiation between marble and brown trout and their hybrids.

Transcriptome profiles were obtained from skin of brown trout (S. trutta), marble trout, and marble trout x brown trout hybrids (F3 generation) exhibiting marble colour pigmentation by using cGRASP 32K cDNA microarray. Significant differential expression was detected for 170 (p < 0.01) gene clones. When marble trout and hybrids were compared to brown trout, three genes were differently expressed. All three genes (Secretogranin II, Mitochondrial 28S ribosomal protein S33 and DNA-directed RNA polymerase II subunit RPB1) showed parallel pattern of transcription.
