Inheritance and joint segregation of biochemical loci in European whitefish, genus Coregonus

Crosses were made with whitefish of Coregonus lavaretus complex and vendace Coregonus albula L. to establish the genetic basis of variation at enzyme loci. The alleles of Gpi-2, Gpi-4, Ldh-1, Mdh-2, Mdh-3, 4 and Pgm-2 were found to segregate in a simple Mendelian fashion in whitefish. Ck-1 and Mdh-3, 4 were found to segregate normally in vendace. The results of 10 cases of pairwise segregation between these loci are presented. All pairs revealed random assortment except Gpi-4 with Ldh-1, which showed almost complete linkage.
