The structure and genetic diversity of the Spanish dairy breeds, Churra and Manchega, is analyzed by means of DNA lactotypes observed in alpha(s1)-, alpha(s2)-, beta- and kappa-ovine caseins. The inter-racial distribution of the casein genotypes is also analyzed. The two breeds differ quantitatively as well as qualitatively in their lactotypes. The proportions of unique lactotypes in Churra and Manchega reveal a high degree of within breed diversity. Breed genetic diversity is greater in Manchega (1.28) than Churra (1.53). The probability combination test indicates the existence of significant inter-racial differences.

关于 Churra 和 Manchega 绵羊品种 DNA 乳型的简短说明

通过在 α(s1)-、α(s2)-、β- 和 kappa-绵羊酪蛋白中观察到的 DNA 乳型分析西班牙奶牛品种 Churra 和 Manchega 的结构和遗传多样性。还分析了酪蛋白基因型的种族间分布。这两个品种的乳型在数量上和质量上都不同。Churra 和 Manchega 中独特乳型的比例揭示了品种内高度的多样性。Manchega (1.28) 的品种遗传多样性高于 Churra (1.53)。概率组合检验表明存在显着的种族间差异。
