Abstract: We report on a PCR-RFLP procedure for recognising of a silent point mutation of ITGB2 CD18 subunit gene in cattle. Polymorphism screening was performed in a Polish Black-and-White cattle population (n=210). The genotype and allele frequecies were established in the sires and cows. Further research is needed to explain the possible applications of the CD18 silent point mutation as a potential molecular marker for high milk productivity.

Key words: cattle, CD18 gene, silent point mutation, DNA polymorphism.
