摘要

瑞典山地牛(Fjäll)和牛亚群Fjällnära起源于瑞典北部。它们与瑞典南部的传统和商业牛不同。我们分析了来自GGP HD150k SNP阵列的数据，并研究了Fjäll和Fjällnära之间以及Fjällnära不同群体之间的遗传多样性和差异。我们发现Fjällnära可分为四组，它们彼此之间有区别，并与其他Fjäll牛有区别。我们还比较了不同组Fjäll和Fjällnära中包含的一些功能性SNP的等位基因频率。有趣的是，β乳球蛋白B等位基因在Fjällnära牛中出现的频率非常高(94%)，这与Fjäll牛的频率(60%)有显著差异。将较老的Fjäll牛样本与较新的样本进行比较，我们发现Fjäll牛中B等位基因的频率显著增加。

Genetic differentiation between subpopulations of Swedish mountain (Fjäll and Fjällnära) cattle

ABSTRACT The Swedish Mountain (Fjäll) cattle and the subpopulation Fjällnära originates from northern Sweden. They are differentiated from both traditional and commercial cattle from southern Sweden. We analysed data from the GGP HD150k SNP array and investigated genetic diversity and differences between Fjäll and Fjällnära, and between different groups of Fjällnära. We found that the Fjällnära can be divided into four groups, which are differentiated from each other and from the other Fjäll cattle. We also compared allele frequencies between different groups of Fjäll and Fjällnära for some of the functional SNPs included in the SNP array. Interestingly, the B allele of Beta lactoglobulin has a very high frequency (94%) in the Fjällnära cattle, which is significantly different from the frequency in the Fjäll cattle (60%). Comparing older samples of Fjäll cattle with more recent samples, we found a significant increase in the frequency of the B allele in Fjäll cattle.
