POLYMORPHISM of the rabbit kappa kasein gene and its influence on performance traits.
The rabbit κ-casein encoding gene has previously been shown to possess two alleles. The two alleles do not differ in their coding region and in the accumulation levels of mRNA. However they differ greatly with respect to their intronic regions. The rearranged regions in the first and fourth introns were found to be inverse and complementary LINE sequences. The A allele was found to be more frequent in different European breeds. Correlation of the κ-casein genotype with the breeding capacity in a New Zealand White rabbit stock has been examined.
