Content of review 1, reviewed on June 03, 2015

As a general description of the data, most of the text is appropriate and sufficient. Below I indicate a few places where more information should be added.

Discretionary Revisions
Last line page 2: Add “of” after “composite”

Major Compulsory Revisions
Page 4: “[11] for subsets of samples” Why was this done for subsets of samples? Please clarify.
Page 4: It would be good to add a few words to describe the data in Figures 1 and 2. For instance for Figure 1, you state “SNP genotypes were then compared to those obtained using the Illumina BovineHD Beadchip array (770K)”. Please describe what this comparison shows us.
Figure 2: Please add how much variance is explained by PC1 and PC2.
