Genetic control of glucosephosphate isomerase (GPI) in common carp (Cyprinus carpio L.).
In common carp, a freshwater fish species of tetraploid origin, GPI enzymes are present in two variants: GPI-A and GPI-B. GPI-A is coded by two loci segregating for two (GPI-A 1*) and six (GPI-A2*) alleles. Experimental crosses of the ornamental (Koi) variety of common carp revealed that GPI-B is coded by only one locus (GPI-B*). Another GPI-B* locus must have been silenced in the process of functional diploidization. It was also shown that the GPI-A2* locus segregated independently from the GPI-B* locus, demonstrating that the loci are located on different chromosomes.
