The rabbit kappa-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 kappa-casein genotype with the breeding capacity in a New Zealand White rabbit stock has been examined.
先前已证明兔κ-酪蛋白编码基因有两个等位基因。这两个等位基因在编码区和mRNA积累水平上没有差异。然而，它们在内含子区域有很大差异。在第一和第四内含子中的重排区域被发现是反向互补的长散在核元件序列。在不同欧洲品种中发现A等位基因更为常见。已研究了κ-酪蛋白基因型与新西兰白兔种群繁殖能力的相关性。
