Application of Genomic Data to Map Genetic Diversity and Enable Genetic Improvement in African Cattle, With Particular Reference to Smallholder Dairy Cattle - Dataset

This is a metadata only record, for enquiries about the dataset described in this record, please contact Karen Marshall, International Livestock Research Institute (ILRI), [e-mail]. The data is SNP genotype data of more than 4,000 animals representing European Bos taurus dairy breeds, East and West African indigenous and crossbred dairy cattle sampled from different countries were used for this study. The samples were genotyped on either the Illumina BovineSNP50 BeadChip array (Illumina Inc., San Diego, CA, USA) comprising 54,609 SNPs or the Illumina BovineHD Beadchip (Illumina Inc., San Diego, CA, USA) containing 777,962 SNPs.本记录仅包含元数据。若需查询本记录所描述的数据集，请联系国际家畜研究所（International Livestock Research Institute, ILRI）的Karen Marshall，邮箱地址：[e-mail]。本数据集为单核苷酸多态性（Single Nucleotide Polymorphism, SNP）基因型数据，研究纳入了4000余头个体，涵盖欧洲普通牛（Bos taurus）乳用品种，以及来自不同国家的东非、西非本土奶牛与杂交奶牛群体。所有样本均通过两种芯片完成基因分型：一是Illumina BovineSNP50基因分型芯片（Illumina公司，美国加利福尼亚州圣地亚哥），包含54609个SNP位点；二是Illumina BovineHD基因分型芯片（Illumina公司，美国加利福尼亚州圣地亚哥），包含777962个SNP位点。
