Özet

A new alternative genotyping method based on PCR-SSCP was developed for direct differentiation of the CSN1S1 alleles B and C in the coding region. In addition a PCR-RFLP test based on a MaeIII restriction site in the promoter region of CSN1S1, reported in the literature as an alternative test for the differentiation of CSN1S1*B and C was used and the alleles named b and c. Genotyping of 649 animals belonging to 17 European and Turkish cattle breeds showed differences in occurrence and frequency of the alleles. CSN1S1*B occurred in all breeds with frequencies varying from 0.50 in Anatolian Blackup to 1.0 in e.g. Ayrshire. CSN1S1*b on the other hand varied from 0.63 in Jersey, 0.97 in Ayrshire to 1.0 in e.g. Angler.
