Evidence of linkage between the loci of albino gene (i) and color interferer (ci), was given by the data scored on both advanced embryos and adults of hybrids. The two were linked in the repulsion phase, i.e., i, +ci in original albinos and +i, ci in the ci-stock.
Two recombinant fish in which one chromosome is linked in the coupling phase (i, ci) were detected out of eleven albino males among F2 of i, +ci/i, +ci×+i, ci/+i, ci. Using these fish as progenitors, ici-homozygotes were bred. Employing appropriate mating types, recombinants (+i, +ci) were observed in three matings of i, ci/i, ci×i, +ci/ +i, ci. The recombination value was found to be 4.6±1.2 percent.
