Summary of all cattle included in the study as well as the data generated from clonal sequencing.

<p>* Fetus in approximately the fourth month of gestation</p><p>** Fetus in approximately the eighth month of gestation</p><p>NA: not applicable, not part of a family</p><p>Unique PI ID numbers were assigned to animals as well as an additional designation (Family ID) for those animals that were part of a family within this sample. F denotes the family and G denotes the generation. For example, F1-G2 is the second generation of family 1. Furthermore, PI4 is the fetus of PI3 and PI10 is the fetus of PI9. The BVDV genotype was determined by comparison of the consensus E2 sequence to the reference sequences depicted in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0131972#pone.0131972.g001" target="_blank">Fig 1</a>.</p><p>Summary of all cattle included in the study as well as the data generated from clonal sequencing.
