Summary Genetic polymorphism of bovine lysozyme (LYZ) genes was investigated by analysing restriction fragment length polymorphism (RFLP). The analysis revealed three RFLP loci designated LYZ1, LYZ2 and LYZ3. Each system included two or three allelic variants. Evidence for close genetic linkage of the three loci was found. There was also a significant linkage disequilibrium among the three loci in a sample of about 200 breeding bulls from one breed. No statistically significant association was found between LYZ RFLPs and breeding values of bulls for disease or milk production traits.
