Allozymic variation as an estimate of heterozygosity in Belgian pig breeds

An electrophoretic survey of 13 enzymes corresponding to 19 loci has been carried out in Belgian Landrace and Pietrain pig breeds. Four of these enzymes have been shown to exhibit electrophoretically detectable polymorphism. The average heterozygosity per locus was found to be 0.066 in the Belgian Landrace and 0.028 in the Pietrain pigs.
