Abstract

ABSTRACT Icelandic cattle is believed to have been brought from Norway during the settlement of Iceland around AD 870-930. Previous research on genetic relationships has indicated that Icelandic cattle is most related to northern Nordic indigenous breeds. Using single nucleotide polymorphism genotype data from Icelandic cattle and 29 Northern and Western European cattle breeds, we studied relationships and admixture among these breeds, and assessed population structure in Icelandic cattle. Population structure analysis through principal component analysis, estimation of ancestry, and analysis of patterns of population splitting and mixing revealed that Icelandic cattle are most related to three Finncattle breeds (Eastern, Northern and Western Finncattle), and Swedish Mountain cattle. Icelandic cattle has very low levels of admixture. We observed very limited population structure in Icelandic cattle. The observed structure was due to variable sire contributions. Over 1000 years of almost complete isolation has made Icelandic cattle highly genetically distinct from other cattle breeds.

冰岛牛与北欧和西欧牛品种的关系、杂交和种群结构

冰岛的牛被认为是在公元870-930年冰岛人定居期间从挪威带来的。先前对遗传关系的研究表明，冰岛牛与北欧北部的本土品种关系最为密切。利用冰岛牛和29个北欧和西欧牛品种的单核苷酸多态性基因型数据，研究了这些品种之间的关系和杂交，并评估了冰岛牛的种群结构。种群结构分析通过主成分分析、祖先估计和种群分裂和混合模式分析表明，冰岛牛与三个芬兰牛品种(东部、北部和西部芬兰牛)和瑞典山地牛最接近。冰岛牛的混合物含量很低。我们观察到冰岛牛的种群结构非常有限。观察到的结构是由于不同的贡献。1000多年来，冰岛牛几乎完全与世隔绝，这使得冰岛牛在基因上与其他牛品种截然不同。
