Kappa-casein polymorphisms among cattle breeds and bison herds
We identified the Hind III restriction site polymorphism of K-casein in cattle reported by Pinder et al. ( Animal Genetics 22, 11, 1991) and found an additonal polymorphism ( Rsa I) in cattle and bison. The Hin dIII and Rsa I restriction sites were mapped and three haplotypes (alleles) were identified. Preliminary screening of 39 cattle and 71 bison revealed one allele restricted to cattle, one restricted to bison, and one shared by the species. No fixed allelic differences were observed among cattle breeds or among bison herds or subspecies.
