High-resolution population structure of cattle.

<p>Network visualization of 2,457 cattle. Each cattle is represented by a node; with individual node size associated with <i>gc</i>_<i>j</i>, whilst the node color (dark blue) indicates top 55 key contributors. The thickness of edges varies in proportion to the genetic distance to visualize individual relationships within the population. The network structure of indicates that key contributors are well distributed within the population and highlights the existence of a substructure according to less influential bulls (dashed circle).
