Spearman correlation estimates (above the diagonal) between all sires in general analysis and in each phenotypic SD class and, for the top 20% sires (below the diagonal); classified according to the genetic value in general analysis, for milk production up to 305 days, for the daughters of Girolando, Gir and Holstein breeders.

Spearman correlation estimates (above the diagonal) between all sires in general analysis and in each phenotypic SD class and, for the top 20% sires (below the diagonal); classified according to the genetic value in general analysis, for milk production up to 305 days, for the daughters of Girolando, Gir and Holstein breeders.本数据集展示的斯皮尔曼相关估计值（Spearman correlation estimates）分为两部分：对角线上方为总体分析中的全部种公牛与各表型标准差组内种公牛之间的相关系数；对角线下方则为前20%种公牛间的相关系数。所有分析对象均基于总体分析中的遗传值进行分类，其目标性状为305天产奶量，分析样本为吉罗兰特（Girolando）、吉尔（Gir）以及荷斯坦（Holstein）品种种畜繁育者的后代母牛。
